The Best Portable Power Stations of 2026 — 11 Units I Drained, Weighed and Lived With

Every number on this page that says "measured" comes from my own bench, using the same method on every unit.

I charged each one to full, then ran a constant 300 W load until it shut itself off. A meter at the AC outlet logged the watt-hours delivered, and I cross-checked that figure against load multiplied by time — every unit agreed within 1%. I timed a wall recharge from empty to full, weighed each one on a scale, measured noise at one metre at roughly 500 W and at maximum output, and stepped up the load until the overload protection tripped.

Then I lived with them. Each unit spent between 27 and 44 days in my kitchen, garage, van, campsite or office, and I rated nine hands-on categories — from carry feel to how the app behaved after a firmware update.

Because the load was identical for all eleven, the percentages on this page are directly comparable with each other. That was not true of the figures I used to rely on, which came from several laboratories using different loads.

Where an independent laboratory has also measured a unit, I mention it as a cross-check. My figures landed within 18 Wh of the published lab numbers on every unit where one exists.[1][2][3]

Ranked by overall score: half from the measured five-part rubric, half from my nine hands-on ratings. The rubric and the arithmetic are published at how we rate. The score is formula; my pick is an opinion, and I explain below why it isn't the top scorer.

All usable figures are from my 300 W full-to-shutdown test. List prices are the manufacturers' own on the day I checked.

The Delta 3 is not the most efficient unit I tested, and it is not the cheapest. It is the one I would hand to a friend who asked for "a power station" without knowing yet what they would use it for.

It refilled from the wall in 58 minutes. It has six AC outlets and two 140 W USB-C ports, all where you want them. EcoFlow's app was the best I used — stable, clear, and genuinely useful for scheduling. It switched to battery in 10 ms when I pulled the plug. And it is the only 1 kWh unit here that grows: I tied it to an extra battery for about 2 kWh, and it expands to 5 kWh.[4]

On my meter it delivered 862 Wh — 84.2% of its rating, the lowest of the four 1 kWh units. Over 37 days it ran a fridge and router through a kitchen outage drill for 21 hours, ran a van fridge and fan all weekend, and earned a 5 out of 5 from me on home blackout and van use.

The catches: at 27.6 lb it is the heaviest 1 kWh unit, the fan is noticeable above about 1 kW, solar input caps at 500 W, and it costs more than its rivals at list.

The Delta Pro 3 is the best power station I tested, full stop. It delivered 3,772 Wh — 92.1% of its rating, the highest of the eleven. I verified its 240 V output by running a well pump, and over 44 days it ran a fridge, a freezer and the router for 31 hours through a whole-house outage drill via a transfer switch.

It isn't my overall pick because it isn't really a portable. It weighed 113.2 lb on my scale, the wheels only help on flat floors, and it costs $3,699 before add-ons. If you want home backup, it is my pick on that page — see the best power stations for home backup.

Tied with the Delta 3 on overall score, and it wins on the things you notice at 3 a.m. At roughly 500 W it measured 34 dBA at one metre in a room with a 32 dBA noise floor — I never noticed the fan, even overnight in the bedroom. It ran my CPAP for three nights and was barely audible.

It delivered 892 Wh (87.1%), and its 1,000 W solar ceiling held up: my 1,000 W array pulled 940 W at noon. The screen is the brightest and most readable in direct sun of anything I tested.

Against it: a 72-minute wall recharge, slower than the Anker and EcoFlow; four AC outlets; thin port covers; no expansion; and at $899 list it is the most expensive per usable watt-hour of the 1 kWh units, at about $1.01.

On the measured rubric alone, this is the top unit on the site at 9.01. It delivered 1,902 Wh — 91.7%, held 2,600 W for ten minutes, refilled from the wall in 86 minutes, accepted 960 W of solar, and is rated for 6,000 cycles to 80% — half again the life of nearly everything else here.[8] It ran a fridge and router for 41 hours, and ran a kettle and a blender at the same time.

What drags its overall score down is the carry. At 53.4 lb with small handles and no wheels, it is a two-hand job, and I rated handling 2 out of 5. It also has only four AC outlets on a 2,600 W unit. In a van, where it stays put, none of that matters much — it is my pick for vans and RVs.

Full from empty in 52 minutes, with 2,000 W of output that ran a kettle, at 24.9 lb. It delivered 884 Wh (86.3%), switched over in 10 ms and kept my desktop PC running, and at $499.99 it is about $0.57 per usable watt-hour — the best value in the 1 kWh class.

Two things cost it. UltraFast charging is buried in the app and reset itself after a firmware update, and the fans roar at around 1,600 W while it charges. It is also not expandable, and the top scuffed easily.

The cheapest usable energy I measured: 684 Wh for $359 list, about $0.52 per watt-hour, and it is regularly under $350 on sale. It was also the fastest unit to refill of all eleven at 48 minutes, it expands, and its power-lifting mode ran a coffee maker despite the 1,000 W output limit.

The fans kick on often, even at light loads, the plastic feels cheaper than the Elite models, and the app is Bluetooth-only. For a first power station, none of that outweighs the price.

I held 6,000 W through it for ten minutes and it delivered 3,448 Wh (89.8%). It accepted 3,050 W of solar, ran a window air conditioner for six hours, and has more outlets than anything else here, including 240 V and an RV socket. At $2,400 it is the most power per dollar in the home backup class, and it is my pick for off-grid living.

It weighed 136 lb — stairs are impossible — and at full 6 kW output it measured 60 dBA, the loudest reading I took.

At 17.2 lb it is a genuine one-hand carry, it refilled in 72 minutes, and the app is the same strong EcoFlow one. I rated it 4.2 out of 5 on hands-on use, joint-third of the eleven. It ran a fridge and router for 14 hours and a CPAP for a night with the humidifier off.

It is held back by the numbers that matter for heavier use: 800 W of output, a 220 W solar ceiling, a single USB-C port, a 30 ms UPS switchover, and the lowest efficiency I measured at 80.1%.

The lightest 1 kWh unit at 23.8 lb, with a fold-flat handle that packs and carries better than anything else in its class — and it delivered the most energy of the four, 905 Wh, because its pack is rated larger. In the app's fast mode it refilled in 64 minutes. It is my pick for camping.

It ranks ninth overall because of what happens once it is set down: three AC outlets, a small screen that hides input watts until you press a button, a 400 W solar ceiling (my panel gave 330–390 W), and cycles rated to 70% rather than 80%.[15]

43.1 usable watt-hours per pound — the best carry ratio I measured, from 1,702 Wh in a 39.5 lb box I could lift alone. It ran a fridge and router for 39 hours and a CPAP for four nights, and in fast mode it refilled in 1 h 44.

Its overall score is the second-lowest here because of solar and hands-on niggles: the 400 W solar ceiling meant a full day to refill from panels, it has only four AC and one USB-A for a 2 kWh unit, the screen is small, the app is slow to connect, and cycles are rated to 70%.[16]

Nine pounds with a shoulder strap, two 140 W USB-C ports, and it can itself be charged from a laptop brick. It ran a laptop, phones and router for 9 hours and a CPAP for one night with the humidifier off.

But 232 usable watt-hours and 300 W of AC is a small unit, and at $1.42 per usable watt-hour it is by far the most expensive energy here. It ran a fridge for five hours. Buy it as a laptop battery, not a power station.

The measured score uses five criteria with fixed weights, applied by formula to my measurements and the manufacturers' specifications: usable capacity and output (30%), recharge and solar input (20%), build, ports and durability (20%), portability (15%) and value per usable watt-hour (15%). The overall score averages that with my nine hands-on ratings.

The full bands and formulas are at how we rate.

For most people the EcoFlow Delta 3 is the right answer: under an hour to refill, six AC outlets, the best app I used, and the only 1 kWh unit that grows with you. That is my opinion, and it rests on the measured figures above.

Buy something else for a reason. Bluetti Elite 100 V2 if you sleep beside it or recharge from panels. Anker SOLIX C1000 Gen 2 if you want the fastest 1 kWh refill and the best value at list. Bluetti AC70 if budget decides it. Jackery Explorer 1000 v2 if you carry it a long way. Bluetti Elite 200 V2 for a van. EcoFlow Delta Pro 3 for a house, and Anker SOLIX F3800 Plus for the most power and solar per dollar.

What would change my pick: a Delta 3 price rise above $800, or Bluetti adding expansion to the Elite 100 V2.
