The Best Portable Power Stations

This is the unit we point most people at, and the reason is a single number: 45Wh per pound. 1,070Wh at 23.8 lb is the best published capacity-to-weight in the 1kWh class, and it is what makes this the unit that gets carried rather than the unit that gets left in the garage.

The capacity lands where most people actually need it. A 12V fridge at a realistic duty cycle draws about 430Wh a day, so this is two nights of camping with margin, or an overnight household outage with the fridge and the router covered. 1,500W continuous and 3,000W surge handles everything short of sustained heating.

Jackery publishes a 1.7-hour wall recharge, a one-hour emergency charge through the app, and below 22 dB in silent mode — the quietest figure here, which matters more at a campsite than on a spec sheet. What you give up against rivals is solar input (400W is the lowest of the 1kWh units) and outlets (two).

2,000W continuous from a 24.9 lb box is the standout number on this page. It is more sustained output than anything else here at anywhere near the weight, and it is what an induction hob, a 1,500W kettle, a hair dryer or a full-size microwave all need.

The 49-minute full recharge at up to 1,600W input is the fastest here by a wide margin, and it changes how you use the unit: an hour at any outlet is a full battery, which effectively multiplies 1,024Wh across a multi-stop trip. The 10 ms UPS switchover is the fastest too, making it the best of these at doubling as a home backup between trips.

Anker dropped expandability in this generation — the previous C1000 takes a second 1,056Wh pack and the Gen 2 does not, which its own FAQ confirms. It also has only two AC outlets against the older model's six. Both are real regressions and worth weighing if your loads are growing.

Up to 1,000W of solar input across two MPPT channels is the highest ceiling in the 1kWh class, and it is the spec that matters for anyone who intends to be away from an outlet for more than two days. A fridge and devices come to roughly 520Wh a day; a properly sized array into a unit that will accept it puts back more than that before lunch.

It also expands to 5kWh, which makes it the most future-proof unit here. The head unit you buy for weekend camping is the same one that serves a van build two years later — that is the argument, and it is a good one.

The honest caveat: the 1,000W headline needs two separate panel arrays, since each MPPT input caps at 500W. One array gets you 500W, which is still joint-best here but half the marketing number. At 27.6 lb it is also 3.8 lb heavier than the Jackery for slightly less battery.

1,152Wh is the largest battery in the 1kWh class and 3,500+ cycles to 80% is the longest published cycle rating in our whole registry. Four AC outlets, a 12V socket and a wireless charging pad make it the most practically equipped unit here for a site that runs several things at once.

The 1,440W AC input refills it in 1.3-1.8 hours, and the 20 ms UPS switchover means it works as a bedside or desk backup at home. For a unit that will be cycled every trip for a decade, the cycle rating is not a spec-sheet trophy — it is the reason this ends up cheaper per cycle than anything else here.

And it weighs 35.27 lb, which is 11.5 lb more than the Jackery for 82Wh more battery. That is the trade in one sentence, and where you land on it depends entirely on whether the unit is carried or driven.

10.4 lb is the entry point at which a power station stops being cargo and starts being something you just bring. 286Wh covers phones, lights, a laptop evening and a CPAP for a night without the humidifier — which is genuinely the full load list for a lot of people who think they need a kilowatt-hour.

What makes it more than a small battery is the 858Wh expansion ceiling with a wire-free extra pack. Carry the light version for a weekend, bring the extra for a longer trip. Nothing else at this weight scales that way.

600W of AC output with 1,200W available through X-Boost is honest about what it is. EcoFlow's US product page does not publish a warranty term, which is a real gap on a purchase you expect to keep — worth asking the retailer about before you commit.

If you are not yet sure whether you need one of these, this is the cheap, light way to find out. 288Wh and 300W of output covers phones, a tablet, string lights and a laptop evening, and at roughly 8.2 lb it is the lightest thing here.

The 100W USB-C port is the underrated feature: a modern laptop charges straight from it without the inverter running at all, which is more efficient, quieter and kinder to the battery than pushing the same power through the AC side.

Its ceiling is genuinely low and worth being clear about. 300W of output means nothing that heats. 100W of solar input means a panel is a trickle rather than a refill. Bought as a devices unit it is excellent; bought hoping it stretches, it disappoints on the first trip.

2,048Wh is where a portable unit stops being an evening's cover and becomes a genuine day-and-a-half of a full household load. A normal refrigerator needs roughly 1,200Wh over 24 hours; this covers that plus the router, the phones and the lamps with room left.

It expands from 2kWh to 6kWh with up to two extra batteries and takes up to 1,000W of solar, so it grows in both directions. 2,400W continuous with 3,400W available through X-Boost covers a fridge, a microwave in bursts and a furnace blower.

EcoFlow does not publish a weight or a surge figure on its DELTA 2 Max product page, and rather than fill those in from a retailer listing we have left them blank. Treat this as a unit that lives where you put it — this capacity class is universally in the 50-60 lb range, and it is not something you carry to a campsite.

This is a different category of object. 3,840Wh, 6,000W continuous at 120V and 240V, a 9,000W surge, NEMA 14-50 and L14-30 outlets, and expansion to 53.8 kWh across six batteries. It will run a well pump, a 240V appliance, or a genuinely large fraction of a house.

2,400W of solar input across two 1,200W channels means it can be recharged meaningfully from a roof array rather than trickled, which is what makes multi-day off-grid operation realistic rather than theoretical.

It weighs 132.3 lb including the wheels, and the wheels are an admission rather than a solution — they work on a driveway and a garage floor, not on grass, gravel or stairs. Buy this for a house. Do not buy it imagining a campsite, and do not buy it at all unless your outages justify the step up from a 2kWh unit.
