Power Station Weight Guide

August 13, 2026

6 Views

Measured weights for our reviewed power stations ranged from 7.4 to 188 pounds. Compare capacity to weight by class, and find the lightest unit for the power you need.

What each capacity class actually weighs, which machines carry the most energy per pound, and how to work out what you can realistically lift.

Weight determines more than any other physical specification how a power station is used. A machine you can carry goes camping, moves between rooms, and rides in a car boot. A machine you cannot get installed once and stay there.

We have weighed all the power stations we have reviewed. The lightest is 7.4 pounds. The heaviest is 188. Between those two extremes sits a fairly predictable relationship between capacity and mass – and a set of genuine outliers in both directions that are worth knowing about.

The Short Answer

Roughly what each capacity class weighs, from our measured data:

Under 400Wh – 7 to 14 pounds. One hand carried any distance.
400 to 700Wh – 12 to 22 pounds. One hand, short distances.
700 to 1,200Wh – 17 to 37 pounds. One hand for a strong adult; two for comfort.
1,200 to 1,700Wh – 33 to 72 pounds. Two hands and a plan for stairs.
1,700 to 2,300Wh – 35 to 67 pounds. Two hands; the range here is unusually wide.
2,300 to 4,200Wh – 57 to 149 pounds. Two people for most of them.
Above 4,200Wh – 124 to 188 pounds. A delivery-and-installation exercise.

Weight by Capacity Class: What the Data Shows

The relationship between capacity and weight is real but loose. Within every class, the heaviest machine is roughly double the lightest, which means capacity alone tells you surprisingly little about what you will be carrying.

Capacity Class	Weight Range	Median	Typical Use
Under 400Wh	7.4 – 14.2 lbs	9 lbs	Backpacking, phones, laptops, camp lighting
400 – 700Wh	12.3 – 22 lbs	16.5 lbs	Car camping, weekend trips, CPAP overnight
700 – 1,200Wh	16.8 – 37 lbs	27 lbs	Camping, light home backup, a fridge for a night
1,200 – 1,700Wh	33 – 72 lbs	40 lbs	RV, overlanding, essential-circuit backup
1,700 – 2,300Wh	35 – 67 lbs	48 lbs	Home backup, multi-appliance loads
2,300 – 4,200Wh	57 – 149 lbs	88 lbs	Whole-circuit backup, permanent installation
Above 4,200Wh	124 – 188 lbs	132 lbs	Whole-home systems on a transfer switch

The Number That Matters: Watt-Hours Per Pound

Raw weight tells you what you can lift. Watt-hours per pound tells you whether the weight is buying you anything.

Across our review, the average is 36.9 watt-hours per pound. The best machine we have measured returns 57.4. The worst returns 20.1, meaning it carries less than half the energy per pound of a well-designed system, regardless of size.

The most energy-dense machines we have measured

Model	Wh per lb	Weight	Capacity
Anker SOLIX S2000	57.4	35 lbs	2,009Wh
Bluetti Elite 300	52.9	57 lbs	3,014Wh
Jackery SG HomePower 3000	52.1	59 lbs	3,072Wh
Anker SOLIX C2000 Gen 2	50.0	41 lbs	2,048Wh
Pecron F3000	48.8	63 lbs	3,072Wh
Bluetti Fridge Power	46.9	43 lbs	2,016Wh
Jackery HomePower 3600 Plus	46.5	77 lbs	3,584Wh
Pecron E2400LFP	45.5	45 lbs	2,048Wh
EcoFlow River 2 Pro	45.2	17 lbs	768Wh
AFERIY P310	43.6	88 lbs	3,840Wh

The comparison worth making

The Anker SOLIX S2000 has a capacity of 2,009 Wh and weighs 35 pounds. The Bluetti AC240 has a capacity of 1,536 Wh and weighs 72 pounds.

The Anker carries 30% more energy for less than half the weight. Both are current machines from major brands, and both cost real money. Weight efficiency is a design decision, not a physical constant.

The least energy-dense machines we have measured

Model	Wh per lb	Weight	Capacity
BougeRV Flash 300	20.1	14.2 lbs	286Wh
Bluetti AC500 + B300S	20.6	149 lbs	3,072Wh
Bluetti AC240	21.3	72 lbs	1,536Wh
Bluetti AC300 + B300K	21.8	127 lbs	2,764Wh
Bluetti EB3A	26.5	10.1 lbs	268Wh
Enphase IQ PowerPack 1500	27.9	55 lbs	1,532Wh
Anker SOLIX F3800 Plus	28.2	136 lbs	3,840Wh
Anker SOLIX F3800	29.1	132 lbs	3,840Wh

Two patterns explain most of the items on this list. Modular systems like the Bluetti AC300 and AC500 have an inverter head that holds no cells, so the weight-to-capacity figure looks poor until you add battery modules. And split-phase machines like the Anker F3800 pair a very large inverter with a moderate pack.

In both cases, the weight is buying capability rather than capacity, which is a fair trade if you need that capability and dead weight if you do not.

What Actually Makes a Power Station Heavy

1. Cells are most of it, but not all of it

The battery pack is the single largest contributor to weight, which is why capacity and mass track each other broadly.

It is worth correcting the widely circulated claim that lithium iron phosphate cells are 20-30% heavier than older NMC cells for the same capacity.

Our data does not support that at the product level. Across 76 LiFePO4 machines, the average is 36.9 watt-hours per pound. Across the five NMC machines, the average is 37.3, with a difference of about one percent.

At the raw cell level,l NMC is genuinely more energy-dense. By the time it is packaged into a finished product with a casing, an inverter, a charge controller,er and cooling, that advantage largely disappears. Choose chemistry on cycle life, not on weight.

2. The inverter is the second-largest factor

A bigger inverter needs bigger transformers, bigger heatsinks, and more cooling, and all three add mass.

This is why split-phase machines are so heavy. The Anker SOLIX F3800 pairs a 6,000-watt inverter with a 3,840Wh pack and weighs 132 pounds, whereas the Jackery HomePower 3600 Plus pairs a 3,600-watt inverter with a similar 3,584Wh pack and weighs 77.

Fifty-five pounds of difference for a capacity that is nearly identical. What the extra mass buys is 240-volt output and twice the continuous power.

3. Modular architecture shifts weight rather than removing it

The Bluetti AC300 and AC500 completely separate the electronics from the cells. The head unit contains the inverter but no battery; capacity comes from modules stacked beneath it.

Head plus one module comes to 127 pounds on the AC300 and 149 on the AC500, which reads terribly as a weight-to-capacity figure. But the system splits into two liftable pieces rather than presenting as one immovable object, making it considerably more feasible to get it down to a basement or over a threshold than a sealed machine of the same mass.

If you are moving a large system through a house, that separation matters more than the total on the scale.

4. Casing and handles account for the rest

Machines built for job sites and vehicles use thicker casings and stronger frames, adding weight without increasing capacity.

It is not wasted weight if the machine gets knocked about. It is wasted weight if it lives in a cupboard.

Weight by Use Case: What You Actually Need to Carry

Backpacking and hiking

Under 15 pounds, which in practice means under 400Wh. Anything more, and the weight defeats the purpose.

The EcoFlow River 2 is the lightest machine we have weighed at 7.4 pounds for 256Wh.
The CTechi 240Wh weighs 7.9 pounds, and the Energizer 320Wh weighs 9 pounds, offering more capacity in the same class.
Expect to run phones, a laptop, camp lighting, and a small fan. Not a fridge, not a kettle.

Car camping and weekend trips

Fifteen to thirty pounds covers the 400 to 1,200Wh range, and this is where most camping buyers should be looking.

The EcoFlow River 2 Pro is the standout on density here: 768Wh in 17 pounds, or 45.2 watt-hours per pound, which beats machines three times its size.
The Oukitel P501 holds 505 Wh in 12.3 pounds, and the Bluetti EB70 offers 716 Wh in the low twenties.
At this weight, one person can load and unload the machine repeatedly without it becoming a chore.

Overlanding and RV use

Thirty to fifty pounds is the practical ceiling for a machine that gets moved in and out of a vehicle regularly. Above that,t it becomes a fixture in the vehicle rather than a portable item.

The Anker SOLIX S2000 is the outstanding choice: 2,009Wh in 35 pounds, the best weight-to-capacity ratio we have measured.
The VigorPool Captain 1200 holds 1,280 Wh in 33 pounds and returns 99% of it through its 12-volt output, which suits vehicle loads.
The Anker SOLIX C2000 Gen 2 gives you 2,048Wh in 41 pounds with a 7.2-millisecond switchover.
Check your vehicle payload as well as your own back. Fifty pounds in a roof box changes handling more than fifty pounds in a boot.

Home backup that stays in one place

Above fifty pounds, weight stops being about carrying and starts being about installation. The questions become: can it get through the door, down the stairs, and into the space you have chosen?

The Jackery SG HomePower 3000 is unusually manageable for its class at 59 pounds for 3,072Wh.
The EcoFlow Delta Pro Ultra is the heaviest machine we have measured at 188 pounds, in a single sealed body that does not come apart.
Modular systems are worth considering here specifically because they separate. A 127-pound Bluetti AC300 arrives as two liftable pieces.

Decide the location before you order. Moving a 130-pound machine after installation is a two-person job with a plan, and moving a 188-pound one is a delivery problem.

Air travel

Weight is not your constraint here; capacity is, and airline limits are strict.

Lithium batteries above 100 watt-hours generally require airline approval, and those above 160 watt-hours are typically prohibited in passenger baggage. Every machine in this guide starts at 240Wh.

In practice, no power station in our database can be taken on a commercial flight. Check with the carrier before assuming otherwise, and plan to ship or rent at your destination.

Handles, Wheels and Form Factor

Two machines of identical weight can feel entirely different depending on how they are built to be carried.

Below about 30 pounds, a single top handle is fine, and most machines use one.
Between 30 and 60 pounds, two side handles are far better than one top handle, because they let you lift with both arms and keep the load close to your body. For anything over 60 pounds, look for wheels and a telescoping handle. Several machines at this weight still ship without them, which turns a manageable object into a two-person one.
Modular systems separate into components, which is the most useful form-factor decision at high weights and worth more than any handle design.

Weight distribution matters too. A machine with a low, centered mass is easier to carry than one of the same weight with a high center of gravity, particularly on stairs.

How to Work Out What You Can Actually Handle

Three practical checks before you buy.

Carry test: pick up something of comparable weight (a bag of cement is 55 pounds; a full 5-gallon water container is about 20 pounds) and walk the route the machine will take. Include the stairs.
Frequency test: a weight you can lift once is not necessarily a weight you can lift weekly. If the machine goes camping every fortnight, halve whatever you think your limit is.
Route test: measure the narrowest doorway, the tightest turn, and the highest step between the delivery point and where the machine will live. A 149-pound system that cannot turn a corner is a problem you discover on delivery day.

How We Measure Weight

Figures are the machine’s own weight, without panels, cables, or expansion batteries attached.
Modular systems are quoted as a head unit plus one battery module, since that is the minimum working configuration. Each additional module adds more.
Watt-hours per pound is calculated from rated capacity rather than tested usable capacity, so the figures compare consistently across the whole database.
Where a manufacturer’s imperial and metric figures disagree, we note the discrepancy on the individual model page rather than silently picking one.

The Bottom Line on Weight

Capacity tells you what a machine holds. Weight tells you how it will actually be used, and the two are related more loosely than most buyers expect.

Within each capacity class we have measured, the heaviest machine is roughly twice as heavy as the lightest. That means shopping by watt-hours alone can leave you with twice the weight you needed for the same energy.

Work out the heaviest thing you will carry, how often, and over what route. Then find the most capable machine under that figure. Our per-model pages carry the measured weight for every unit in this guide, and the watt-hours-per-pound table above is the quickest way to spot the machines that use their mass well.
