OUPES Mega 2 Pro Home Backup & Review
2,048Wh of storage, 2,500W continuous output, LiFePO4 cells. Listed at $749 at OUPES.
The OUPES Mega 2 Pro Home Backup & is a home backup systems unit holding 2,048Wh. At $0.37 per watt-hour it is priced below the median for the band, which makes it one of the cheaper ways to buy this much capacity. It uses LiFePO4 cells, so it is built to be kept rather than replaced. It lists at $749 against an $3,119 MSRP.

What the OUPES Mega 2 Pro Home Backup & will run, and for how long
Runtimes below are calculated from the 2,048Wh 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 2,500W continuous rating is left off the list because this unit cannot carry it.
| Load | Estimated runtime |
|---|---|
| Phone charge (12Wh) | 157 charges |
| Wi-Fi router (10W) | 174 hr |
| LED work light (10W) | 188 hr |
| CPAP, humidifier off (40W) | 44 hr |
| Laptop (60W) | 29 hr |
| 12V portable fridge (45W avg) | 39 hr |
| 55-inch TV (90W) | 19 hr 21 min |
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
Switchover to battery is rated at 20ms, fast enough to keep a desktop or a router from dropping.
OUPES does not publish a maximum solar input for this model, so we do not state one.

Where the OUPES Mega 2 Pro 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 OUPES Mega 2 Pro Home Backup & ranks 5 of 21, where 1 is the cheapest capacity in the band. That puts it in the cheapest third, which is the single strongest thing on its spec sheet. 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 OUPES Mega 2 Pro Home Backup & suits
It is a sensible buy for multi-day outages, a work-from-home setup, and running a fridge alongside kitchen appliances in short bursts. It is the wrong tool for central air conditioning and electric heat, which will empty it in under an hour.
OUPES Mega 2 Pro Home Backup & questions
How long will the OUPES Mega 2 Pro Home Backup & run a fridge?
A full-size fridge averages about 50W once you account for the compressor cycling on and off. From 2,048Wh, derated to 85% for inverter losses, that is roughly 35 hr on a full charge. A 12V portable fridge draws less and will run considerably longer.
Can the OUPES Mega 2 Pro Home Backup & be charged by solar?
OUPES does not publish a maximum solar input for this model. Rather than estimate one, we leave it out. Check the manual that ships with the unit before buying panels for it.
Does the OUPES Mega 2 Pro Home Backup & work as a UPS?
It switches to battery in about 20ms. 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 OUPES Mega 2 Pro Home Backup & carry?
OUPES covers it for 1 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 OUPES Mega 2 Pro Home Backup & worth it?
At $749 it works out at $0.37 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
OUPES does not state the rated cycle life, the weight, the maximum solar input 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 OUPES 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.
