ALLPOWERS R3500 Home Backup Review
3,168Wh of storage, 3,200W continuous output, LiFePO4 cells. Listed at $1,424 at ALLPOWERS.
The ALLPOWERS R3500 Home Backup is a home backup systems unit holding 3,168Wh. At $0.45 per watt-hour it is priced about where the rest of the band sits. It uses LiFePO4 cells, so it is built to be kept rather than replaced. This model is discontinued, so stock is whatever is left in the channel. It lists at $1,424 against an $2,099 MSRP.

What the ALLPOWERS R3500 Home Backup will run, and for how long
Runtimes below are calculated from the 3,168Wh rated capacity, derated to 85% for AC loads and 92% for USB and 12V loads to cover inverter and conversion losses. They are arithmetic, not lab measurements, but they are the same arithmetic applied to every unit we track, so the comparison holds. Anything drawing more than the 3,200W continuous rating is left off the list because this unit cannot carry it, though the 4,000W surge rating covers brief startup spikes from motors and compressors.
| Load | Estimated runtime |
|---|---|
| Phone charge (12Wh) | 242 charges |
| Wi-Fi router (10W) | 269 hr |
| LED work light (10W) | 291 hr |
| CPAP, humidifier off (40W) | 67 hr |
| Laptop (60W) | 45 hr |
| 12V portable fridge (45W avg) | 60 hr |
| 55-inch TV (90W) | 30 hr |
Real figures land below these. A fridge cycles rather than drawing continuously, and cold weather costs a lithium pack usable capacity, so treat the table as the ceiling rather than the expectation.
Charging and power delivery
It accepts 1,500W from a wall outlet. Maximum solar input is 2,000W. At 70% of that rating, which is what a fixed panel realistically delivers across a good day, a full charge from empty is roughly 2 hr 16 min of usable sun. Switchover to battery is rated at 15ms, fast enough to keep a desktop or a router from dropping.

Where the ALLPOWERS R3500 Home Backup sits in its band
We track 21 units in the home backup systems band with both a price and a published capacity. They run from $489 to $10,999, and from 1,024Wh to 20,000Wh. On cost per watt-hour the ALLPOWERS R3500 Home Backup ranks 9 of 21, where 1 is the cheapest capacity in the band. That is mid-table: neither the bargain of the band nor the unit you would call overpriced. Ranking on cost per watt-hour deliberately ignores build quality, port selection and warranty, so read it as one input rather than as the answer.

Who the ALLPOWERS R3500 Home Backup suits
It is a sensible buy for whole-circuit backup, extended off-grid stays, and running heavy appliances without rationing them. It is the wrong tool for anyone who needs something genuinely portable, since capacity at this level comes with real weight, and for carrying it any distance on your own, at 93 lb.
ALLPOWERS R3500 Home Backup questions
How long will the ALLPOWERS R3500 Home Backup run a fridge?
A full-size fridge averages about 50W once you account for the compressor cycling on and off. From 3,168Wh, derated to 85% for inverter losses, that is roughly 54 hr on a full charge. A 12V portable fridge draws less and will run considerably longer.
Can the ALLPOWERS R3500 Home Backup be charged by solar?
Yes. It accepts up to 2,000W of solar input. Panels rarely hit their rated figure in the field, so plan on about 70% of the panel rating across a clear day.
Does the ALLPOWERS R3500 Home Backup work as a UPS?
It switches to battery in about 15ms. That is quick enough for a desktop computer, a router or a modem, all of which tolerate a gap in that range without rebooting.
What warranty does the ALLPOWERS R3500 Home Backup carry?
ALLPOWERS covers it for 5 years. Cycle life and warranty are different promises, and the cycle figure is the one that tells you how long the pack stays useful.
Is the ALLPOWERS R3500 Home Backup worth it?
At $1,424 it works out at $0.45 per watt-hour. It costs less per watt-hour than the median unit in its band, which is the strongest argument in its favour. Read the comparison table above against the two closest rivals before deciding.
What is not published
ALLPOWERS does not state the rated cycle life for this model. We list figures rather than estimate them, so those rows stay empty until the manufacturer publishes them. If you need one of them to make the decision, ask ALLPOWERS directly and hold them to the answer.
How we assess these
Every figure on this page comes from the manufacturer, and every derived number, cost per watt-hour and estimated runtime, is calculated the same way for all 437 products we track. That is what makes the comparison meaningful: we are not scoring units against a private impression of them, we are putting published figures side by side and doing the arithmetic in public. Where a manufacturer stays quiet, we say so rather than filling the gap.
