| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 2,280 Wh (48 V, 60 Ah) |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LiFePO4 (LFP) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | Over 80% capacity after 3,500 cycles and over 50% after 6,500 cycles; ALLPOWERS puts the service life at more than 10 years |
| ExpansionExtra battery units that add storage to the same system. | Not published by ALLPOWERS |
| Output | |
| AC output (continuous)The power it can deliver all the time. Add up the watts of what you want to run at once and stay below this. | 4,000 W pure sine wave, 230 V, four AC sockets |
| AC output (surge)A short burst above the continuous rating, for appliances that draw more power when they start. | 6,000 W peak |
| USB-APorts for phones, tablets and small devices. | 2 x 5 V 2.4 A, 24 W maximum; the page also lists 2 x 5 V 3 A / 9 V 2 A / 12 V 1.5 A, 36 W maximum, and says 4 USB outputs in total |
| USB-CPorts for laptops, phones and tablets. Power delivery up to 100 W can charge most laptops. | 5/9/15 V 3 A and 20 V 5 A, 200 W maximum in the specification table; the feature text says 2 USB-C ports of 100 W each |
| Car outletA 12 V socket like the one in a car, for car accessories. | Yes: Car/DC5525 output, 12 V 10 A, 120 W maximum |
| Wireless chargingA pad on the unit that charges a compatible phone without a cable. | No: not part of the maker's specification list |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 2,000 W maximum (230 V, 10 A) |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | 0 to 100% in about 2 hours according to the feature list; the description also quotes a 2.5-hour full charge from 2,000 W of mains or solar |
| Solar inputHow much solar panel power it accepts. A higher figure fills the battery faster on a sunny day. | Three XT60 inputs, 12-60 V, 13 A and 650 W each; 2,000 W maximum in total (40 A maximum) |
| Solar charging timeHow long a full charge takes from solar panels, in the conditions the maker names. | About 2.5 hours for a full charge at the 2,000 W maximum, according to ALLPOWERS |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | Yes: 12 V / 24 V car charging; no power or time given |
| Pass-through chargingWhether it can power devices while it is itself being charged. | Not published by ALLPOWERS (the UPS function keeps devices powered when the mains fails) |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | 15 ms or less in UPS mode |
| Charging modesSettings that trade charging speed against noise or electricity price, such as a quiet mode or a charging schedule. | Three: Fast, Standard and Silent |
| Solar and off-grid | |
| Works with solar panelsWhether you can charge it from solar panels. Yes means a built-in solar input or a compatible solar setup; read the detail for the voltage and power limits. | Yes: three XT60 solar inputs (12-60 V, up to 650 W each, 2,000 W in total). ALLPOWERS says it should not be connected to the AC output of a grid-tied microinverter. |
| Off-grid useWhether the maker describes it running with no grid connection at all, for example in a cabin, van or off-grid home. Backup only means it covers power cuts but needs the grid the rest of the time. | Yes: ALLPOWERS lists home backup, motorhomes, boats, caravans and off-grid power, charged from solar, the car or the mains. |
| Housing and warranty | |
| Dimensions (L × W × H)Check the space before you buy, including room around it for airflow and cables. | 540 × 490 × 300 mm, as listed by ALLPOWERS (axis order not stated) |
| WeightMatters for lifting, wall mounting and moving it. | 40.5 kg |
| Wheels and handleBuilt-in wheels and a pull handle make a heavy unit easier to move. | Yes: rolling design with an extendable handle |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Not published by ALLPOWERS |
| Noise levelFan noise while working. | Not published by ALLPOWERS |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | Not published by ALLPOWERS |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 5 years for power stations (solar panels 2 years, cables 1 year), according to ALLPOWERS |
How long will it run your devices?

The estimate assumes 85% of the rated capacity is usable after conversion losses. ALLPOWERS does not state this figure, so we use a cautious assumption. Real running times vary with temperature, battery age and how each device draws power.
Compatible with
What ALLPOWERS says this product works with. Anything not listed here is not confirmed.
- Solar panels
- Three XT60 inputs, 12-60 V and up to 650 W each, 2,000 W in total. ALLPOWERS recommends its SP039 600 W, SP037 400 W, SF400 400 W flexible, SP033 200 W and SP035 200 W panels.

- Not for connecting to the AC output of a grid-tied microinverter; ALLPOWERS says it should be charged through its DC solar input.
Rules where you live
A portable power station is not wired into your home, so it is simple to use almost anywhere. Connecting one to your home circuits to power the house is different, and the rules for that vary by country. See our country guides for the rules, incentives and prices where you live.

Common questions about ALLPOWERS R4000 V2
What can the R4000 V2 run?
ALLPOWERS rates it at 4,000 W continuous with a 6,000 W peak, enough for most household appliances as long as the start-up surge stays under 6,000 W. Its runtime formula is not suitable for compressor loads such as fridges.
How is the R4000 V2 different from the R4000?
ALLPOWERS lists the same 4,000 W output, 2,000 W charging, dimensions and ports, but 2,280 Wh (40.5 kg) against 3,456 Wh (45 kg).
Is the R4000 V2 the same as a home battery?
No. It is a portable power station that you plug devices into. An installed home battery is wired into your electrics by an electrician. See our guide to plug-in and installed home batteries.
