If you rent, you probably don’t get to choose your stove. But you can choose what sits on the counter. A plug-in (portable) induction hob is a single burner, or sometimes two, that plugs into a wall outlet. You can use it alongside the stove you have, take it with you when you move, and find out whether you like induction before you ever have a say in a kitchen remodel.

The US Department of Energy suggests exactly this: if you’re a renter, or you want to try induction before swapping out your entire cooktop, consider a single-burner induction appliance. (US DOE)

This guide covers how induction works, how to check your cookware in ten seconds, what the energy agencies say about efficiency, and what to look for in a plug-in unit.

How induction works

A gas burner heats the pan with a flame. A standard electric cooktop heats an element or glass surface, which then heats the pan. Induction heats the pan itself.

The DOE explains that induction uses an electromagnetic field that transfers currents directly to the cookware, so the heat is created inside the pan. As soon as you remove the pan, the heating stops. (US DOE) ENERGY STAR describes the same thing: induction uses electromagnetic energy to heat ferromagnetic cookware internally. (ENERGY STAR)

Because the glass top isn’t the heat source, ENERGY STAR says the surface won’t be hot to the touch without a pot or pan in place. A pan that’s just come off the heat will still warm the glass where it sat. (ENERGY STAR)

The magnet test

Induction only works with cookware a magnet sticks to. You don’t need to buy anything to find out what you already own:

1. Take a fridge magnet to your pans.
2. Hold it to the bottom of each pan. If it sticks firmly, the pan should work. ENERGY STAR: if the magnet sticks, it will work with induction. (ENERGY STAR)
3. Check the base is flat. The DOE says pots or pans with a flat bottom that a magnet sticks to will work. (US DOE) A warped pan may not sit well on the glass.
4. If the magnet doesn’t stick, or only barely, assume that pan won’t work on induction.

ENERGY STAR notes that a lot of common cookware may already be compatible, such as cast iron, stainless steel and enameled cast iron, and that many induction-compatible pots and pans have an induction logo on the box. (ENERGY STAR) ENERGY STAR suggests the magnet test precisely if you’re unsure what your cookware is made of.

If you need one new pan, start with the size you use most. One good pan you’ll keep for years beats a matching set that duplicates what you own.

The energy facts

Here is what US energy agencies say, in their words.

Efficiency

• About 85% vs about a third. ENERGY STAR says that with induction, about 85% of heating energy is transferred to what’s in the cookware, compared with only about a third with gas cooking products. (ENERGY STAR)
• Compared with other electric cooktops. ENERGY STAR’s Emerging Technology Award page puts conventional gas and resistance-element cooking tops at about 32% and 75–80% efficiency respectively, and induction at about 85%. (ENERGY STAR)
• The DOE’s summary: induction appliances are up to three times more efficient than gas stoves, and up to 10% more efficient than conventional smooth-top electric ranges. (US DOE)

What that means for a renter’s bill depends on how much you cook, your electricity and gas rates, and what you’d otherwise use. A single plug-in burner used for the evening meal won’t transform a power bill. The DOE says the efficiency can result in lower energy costs, which is a fair way to put it. (US DOE)

Speed

ENERGY STAR says boiling water with induction can take nearly half the time compared with gas, radiant or coil cooktops. (ENERGY STAR) The DOE cites Consumer Reports’ finding that induction cooktops can boil water 20–40% faster than the gas and traditional electric cooktops it tested. (US DOE) The two figures come from different tests; either way, induction is quick.

A cooler kitchen

ENERGY STAR says more of induction’s energy goes into cooking and less heat is released into the kitchen, which can help keep the room cooler. (ENERGY STAR)

Where the “green” part comes from

The efficiency gain is real and measurable. The wider climate effect depends on where your electricity comes from. The DOE says the efficiency can lead to lower rates of air pollution associated with energy generation. (US DOE) If your power comes from a cleaner grid or a renewable electricity plan you can verify, the benefit grows. We don’t call any appliance “eco-friendly” without saying why; see how we judge green claims.

Choosing a plug-in induction hob

ENERGY STAR

ENERGY STAR now certifies electric cooking products, and its criteria include standalone/portable cooktops as well as ranges. ENERGY STAR says certified electric cooking products are 18% more efficient on average than standard models. (ENERGY STAR) Its online Product Finder lets you check whether a specific model is certified. Partners sometimes offer rebates on certified products, which you can look up with ENERGY STAR’s Rebate Finder.

What to check on the listing

• Wattage and plug. Check the hob’s rated wattage on the label and make sure your outlet and plug type match the model sold in your country.
• Your circuit. A plug-in hob on high draws a lot of power. Don’t run it on the same circuit as a kettle, microwave, toaster oven or space heater at the same time, and follow the manual’s instructions on extension cords and power strips. If a breaker trips, stop and ask your landlord.
• Safety listing. Look for a recognized safety certification mark for your country (in the US, a nationally recognized testing lab such as UL or ETL).
• Auto shut-off and pan detection. The DOE says most induction cooktops automatically shut off if a pot or pan isn’t detected. (US DOE) Check the specific model.
• Coil size vs your pans. A large pan on a small coil heats unevenly. The listing should give the heating zone or coil diameter.
• Controls and noise. Check how settings are shown (power levels or temperatures), whether there’s a timer, and what owners say about fan noise.

Renter checklist

• [ ] Check your lease for any rules about cooking appliances.
• [ ] Do the magnet test on your pans first.
• [ ] Find an outlet on a circuit that isn’t shared with other high-draw appliances.
• [ ] Give the hob a stable, heat-safe surface with space around its vents.
• [ ] Keep the manual and receipt; you’ll take the hob with you when you move.

Living with it

• Protect the glass. ENERGY STAR notes most electric and induction cooking tops are glass or ceramic and vulnerable to scratches and cracking. Don’t drag heavy cast iron across it, and skip scouring sponges; soapy water on a cooled top is usually enough. (ENERGY STAR)
• Plastic utensils. ENERGY STAR says melting plastic utensils is less of a concern with induction, because it doesn’t produce significant residual surface heat. The pan itself still gets hot.
• Expect a learning curve. Induction responds quickly. Start a notch lower than you would on gas or coil.

A portable power station’s spec sheet can run to dozens of lines, and most of them don’t matter for most buyers. A handful decide whether the unit will run what you need, for how long, and for how many years.

This guide goes through a spec sheet in the order we read one. It doesn’t rank brands, and any product figure we quote is the brand’s rating, not our measurement.

1. Capacity: watt-hours (Wh)

Watt-hours measure how much energy is stored. It’s the size of the tank. A 1,000 Wh station holds roughly ten times the energy of a 100 Wh power bank.

Some sheets give amp-hours (Ah) or milliamp-hours instead, which don’t tell you the energy without the voltage. The FAA gives the conversion: to calculate Wh, multiply the battery voltage by the amp-hours. (FAA PackSafe) If a sheet lists only mAh, look for the cell or pack voltage, or skip to a model that states Wh plainly.

Usable vs nameplate capacity

The Wh on the box is the battery’s rated capacity. You won’t get all of it out as 230 V or 120 V AC, because the inverter that turns battery power into household current loses some energy as heat. How much varies by model and by load, so don’t assume a figure; if the brand publishes an efficiency or “usable capacity” number, use that. Otherwise, build in some headroom when you size a unit.

A rough planning sum: runtime (hours) ≈ usable Wh ÷ device watts. We show a worked example with a planning allowance in our EcoFlow vs Jackery comparison.

2. Output: watts (W) and surge watts

Rated (continuous) output, in watts, is how much power the station can deliver at once, indefinitely. It decides what you can run, not how long. A big battery with a small inverter still can’t run a kettle that needs more than the inverter’s rating.

Surge (or peak) watts is a short burst above the continuous rating. Motors and compressors, such as those in fridges, pumps and some tools, can draw more for a moment when they start than they do while running. If your device starts and immediately trips the station, surge is the line to check.

What to look for:

• Your device’s label wattage should sit comfortably under the continuous rating.
• Check how the brand defines surge (for how long it lasts), and treat it as a rough guide.
• AC outlet count and type vary between US and Australian versions of the same model. Check the regional spec sheet.

3. Battery chemistry: LiFePO4 (LFP) vs NMC

Most current power stations use one of two lithium-ion chemistries:

• LiFePO4, also written LFP (lithium iron phosphate).
• NMC (lithium nickel manganese cobalt oxide), common in older and lighter units.

Sellers of LFP units pitch it on cycle life. Jackery, for example, says on its own blog that LFP batteries offer 3,000 to 6,000+ charge cycles, compared with 500 to 2,000 for NMC. (Jackery) Treat that as a brand’s general claim, not a guarantee for any one product, and remember that ranges like these depend on the test conditions. Rather than relying on the chemistry name, compare the two numbers that follow from it: the rated cycle life (with its endpoint) and the weight per Wh. Divide weight by capacity to see how much you’re carrying per unit of storage.

Whichever chemistry it uses, a lithium battery needs care. The FAA notes that all lithium-ion batteries are capable of overheating and undergoing thermal runaway, which can be triggered by damage, overheating, water exposure, overcharging or a manufacturing defect. (FAA PackSafe) Follow the manufacturer’s charging and temperature instructions, and stop using a unit that is swollen, damaged or hot to the touch when idle.

4. Cycle ratings, and why the endpoint matters

A cycle rating tells you how many full charge-and-discharge cycles the battery is rated for before its capacity falls to a stated percentage of the original. That percentage is the endpoint, and it changes what the headline number means.

For example, EcoFlow’s user manual for the DELTA 2 gives a cycle life of 3000 cycles to 80%+ capacity. (EcoFlow DELTA 2 user manual, PDF) Another brand might rate a model to 70% remaining capacity instead. Those two ratings aren’t directly comparable: a battery rated to a lower endpoint can quote a bigger cycle count for the same wear.

How to read a cycle line:

1. Find the endpoint. “3,000 cycles” means little without “to 80%” or “to 70%”. If the sheet doesn’t say, ask the brand or treat the number as marketing.
2. Compare like with like. Only compare cycle counts that share the same endpoint.
3. Translate it into your use. A unit cycled once a month will take a very long time to use up thousands of cycles. For occasional backup, warranty length and repair support may matter more than the cycle count.
4. Check the warranty separately. The cycle rating is a design figure; the warranty is what the brand will actually stand behind.

5. Certifications: UL 2743 and what it covers

In North America, the safety standard to look for on a portable power station is UL 2743, the Standard for Portable Power Packs. UL Solutions describes portable power packs as batteries intended for use when normal grid power isn’t available, such as camping or emergencies, charged from an external source and supplying power through outlets such as AC receptacles, USB, DC jacks and vehicle sockets. (UL Solutions)

Three practical points from UL Solutions’ guidance:

• Check who certified it. A listing can come from UL Solutions or from another recognized certification body. The mark should name the standard and the certifier, and you should be able to look the listing up.
• UL 2743 has a size ceiling. UL Solutions says the scope of UL 2743 limits the aggregate capacity for lithium-ion batteries to 20 kWh; a bigger product must be certified to UL 9540 instead.
• A portable power pack isn’t a home battery system. UL Solutions says the correct certification for a stationary battery energy storage system in a home is UL 9540, and that combining individually certified products in the field doesn’t create a certified system. If you plan to wire a power station into your home’s circuits, talk to a licensed electrician about what your local code requires before you buy.

Outside North America, look for the marks your country recognizes.

6. Flying with a power station: the 100 Wh and 160 Wh lines

This is where capacity becomes a rule, not a preference. In the US, the FAA sets these limits for passengers:

• Up to 100 Wh: spare lithium-ion batteries, including power banks, are allowed, but only in carry-on baggage. (FAA PackSafe) The TSA confirms power banks are prohibited in checked bags. (TSA)
• 101 to 160 Wh: with airline approval, a passenger may carry up to two of these larger spares. (FAA PackSafe)
• Over 160 Wh: not allowed in carry-on or checked baggage. (FAA PackSafe)

A typical “home backup” power station is rated well above 160 Wh (the 1 kWh class models in our comparison are around 1,000 Wh), so it can’t fly with you. If you want something you can take on a plane, look for a unit or power bank rated at 100 Wh or less, with the Wh figure printed on it. The FAA also says many airlines set stricter limits, including on how many power banks you can bring, so check your airline before you pack. Outside the US, check your airline and your country’s aviation regulator.

7. The rest of the sheet, quickly

• AC charging input (W) and solar input (W and voltage range): these decide how fast you can refill. Check that any solar panel you plan to use falls within the stated voltage range, not just the wattage.
• Pass-through charging / UPS mode: whether the station can power devices while it charges, and how quickly it switches over in an outage. If you’re relying on it for a modem or a medical device, read the brand’s exact wording on switch-over time and ask the brand before you rely on it.
• Operating and charging temperature ranges: if you camp in the cold or store the unit in a hot garage, check both ranges, and follow them.
• Expandability: some models accept add-on batteries; others can’t be expanded at all.
• Warranty and repair: length, what it covers, and whether parts and service are available where you live.

A one-page checklist

• [ ] List the devices you’ll run and their wattages.
• [ ] Continuous output comfortably above your biggest device; surge enough for anything with a motor.
• [ ] Capacity (Wh) that covers your runtime, with headroom for inverter losses.
• [ ] Cycle rating with its endpoint, compared only to ratings with the same endpoint.
• [ ] A safety certification you can look up (UL 2743 in North America).
• [ ] If you’ll fly with it: 100 Wh or less without airline approval; never over 160 Wh.
• [ ] Charging inputs that fit how you’ll recharge (wall, car, solar).

How we wrote this

• We based the rules sections on the FAA, the TSA and UL Solutions, and linked each one where it’s used.
• We used two brand statements, each attributed and linked, and one real product figure as a brand rating reported by a named independent source, to illustrate cycle endpoints. We didn’t test any units.
• We don’t name a “best” power station here, because the right one depends on what you need to run. Our EcoFlow vs Jackery comparison applies this checklist to two popular models.
• No brand paid for placement. A power station stores energy rather than making it, so we weight longevity (cycle endpoints, warranty, repair) heavily; see how we judge green claims.

EcoFlow and Jackery are two of the best-known names in portable power stations: big rechargeable batteries with built-in outlets for outages, camping, vans and jobs away from an outlet. Both make models from pocket-sized to whole-home backup, so “EcoFlow vs Jackery” really comes down to comparing specific models.

Here we compare the two brands’ popular ~1 kWh models, the EcoFlow DELTA 2 and the Jackery Explorer 1000 v2. We also show how to work out what size you need, so you don’t overbuy.

First, the two numbers that matter

• Capacity (watt-hours, Wh): how much energy is stored. More Wh means longer runtime.
• Output (watts, W): how much power it can deliver at once. This decides what you can run. A 1,500 W kettle needs an output rating of at least 1,500 W, no matter how big the battery is.
• Surge (peak) watts: a short burst for devices that draw extra power when they start up, such as fridges, pumps and some power tools.

For the rest of the spec sheet (cycle ratings, certifications and flying limits), see how to read a portable power station spec sheet.

Working out runtime

A rough estimate: runtime (hours) ≈ capacity (Wh) × 0.85 ÷ device watts.

The 0.85 is our planning allowance for energy lost converting battery power to AC. It’s an assumption, not a brand figure, and real losses vary with the load. DC outputs (USB, 12 V) usually lose less.

Worked example (illustration only): a 1,024 Wh station running a device that draws a steady 60 W gives about 1,024 × 0.85 ÷ 60 ≈ 14.5 hours. Check your own devices’ wattage on their label or with a plug-in power meter. Fridges cycle on and off, so their average draw is lower than the label’s maximum.

Specs as published by each brand or reported by retailers. We have not measured them. Outlet count and voltage differ between US and Australian/UK versions.

What the numbers mean in practice

• Both use lithium iron phosphate (LFP/LiFePO4) batteries. This chemistry is generally rated for many more charge cycles than older lithium-ion (NMC) power stations, which matters if you’ll use it often. The two brands rate cycle life to different end points (80% vs 70% remaining capacity), so the headline cycle counts aren’t directly comparable.
• The DELTA 2 has more continuous output (1,800 W vs 1,500 W). That’s the difference between running some higher-draw appliances or not. Check the wattage of the specific device you care about.
• The Explorer 1000 v2 is lighter and has slightly more capacity. If you’ll be carrying it to a campsite, the roughly 3 lb difference counts.
• The DELTA 2 can be expanded with an extra battery later (sold separately), which is useful if you’re not sure how much backup you’ll need.

Which suits you?

Choose based on what you need to run, not the brand.

• Mostly phones, laptops, lights, or a modem and router during outages: either works. You may not need a 1 kWh station at all. A smaller unit may be enough and cheaper to buy.
• You want to run a higher-wattage appliance (a microwave, a small heater or some power tools): check the appliance’s watts against the continuous output. The DELTA 2’s higher rating gives more headroom.
• You want to expand later: the DELTA 2 supports add-on batteries. Jackery’s expandable option is a different model (see below).
• You’ll carry it a lot: the lighter Explorer 1000 v2.

If you need more

• EcoFlow DELTA 2 Max: about 2,048 Wh and a 2,400 W AC rating (brand-stated). (EcoFlow US)
• Jackery Explorer 1000 Plus: about 1,264 Wh LiFePO4, 2,000 W AC rating, expandable with add-on battery packs (brand states up to 5,056 Wh with three). (Jackery)

How we compared

• We picked each brand’s widely sold model with about 1 kWh of capacity, so the comparison is like-for-like.
• Every figure in the table comes from the brand’s published specs, checked on 31 Oct 2026. Where sources disagreed, or the US page didn’t state a figure, we left it out or said so.
• We have not hands-on tested either unit.
• Neither brand paid for placement, and we currently earn from neither brand directly.

Safety and the “green” question

• Indoor use: battery power stations don’t burn fuel, so they don’t produce exhaust the way a gas generator does. Still follow the manufacturer’s instructions on ventilation, charging and temperature.
• Never connect a power station to your home’s wiring by back-feeding an outlet. Whole-home or circuit backup needs a licensed electrician and an approved transfer switch or inlet. That applies in both the US and Australia.
• Is it “green”? A power station only stores energy. If you charge it from the grid, its footprint depends on your grid’s mix. Charging it from solar panels can lower that. The bigger environmental question is longevity, so cycle life, warranty and repair support matter as much as capacity. Check each brand’s current warranty terms before you buy.
