Specifications
Last checked on 11 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 3,456 Wh (48 V, 72 Ah) |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LiFePO4 |
| 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. | Above 80% capacity after 3,500 cycles and above 50% after 6,500 cycles |
| ExpansionExtra battery units that add storage to the same system. | Not stated |
| 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, 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 |
| USB-APorts for phones, tablets and small devices. | QC 3.0 18 W (5 V 3 A, 9 V 2 A, 12 V 1.5 A), 36 W maximum. The page 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. | Not stated as an output. The 12 V/24 V car input is for charging. |
| Wireless chargingA pad on the unit that charges a compatible phone without a cable. | Not stated |
| Charging | |
| AC chargingHow fast it charges from a wall socket. Higher means a shorter wait. | 2,000 W maximum |
| Time to charge from the mainsHow long a full charge takes from a wall socket. | Full charge in 2.5 hours from 2,000 W mains or solar (ALLPOWERS' figure; conditions not stated) |
| 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 in total |
| Solar charging timeHow long a full charge takes from solar panels, in the conditions the maker names. | 2.5 hours at the full 2,000 W (ALLPOWERS' figure; conditions not stated) |
| Car chargingCharging from a car's 12 V or 24 V socket while driving. Slow, but useful on the road. | 12 V or 24 V car input; no rating or charge time stated |
| Backup switchover (EPS)What happens when the grid fails. EPS means it takes over automatically. | 15 ms or less |
| Pass-through chargingWhether it can power devices while it is itself being charged. | Not stated |
| 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 (21.25 × 19.29 × 11.81 in), as listed by ALLPOWERS (axis order not stated) |
| WeightMatters for lifting, wall mounting and moving it. | 45 kg (99.2 lbs) |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Not stated |
| Noise levelFan noise while working. | Not stated |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | Not stated |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | Not stated on the product page |
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.

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.

Where this information comes from
We have not tested the R4000. Every figure above comes from ALLPOWERS' UK product page, including its specification table, last checked on 11 November 2026. ALLPOWERS also lists an R4000 V2 as a separate model, which we did not use. A value the page does not state is shown as not stated.
We do not show prices, because they change often and differ between sellers.

Common questions about ALLPOWERS R4000
What can the ALLPOWERS R4000 run?
ALLPOWERS rates it at 4,000 W continuous and 6,000 W peak, so most household appliances work. Its own example is a 700 W heater running for about 4.2 hours, at 86% inverter efficiency.
How fast does the R4000 charge?
ALLPOWERS quotes a full charge in about 2.5 hours from 2,000 W of mains or solar power. Three separate XT60 solar inputs take up to 650 W each.
Is the R4000 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.
