Anker SOLIX F3000
- CNET, which earns commission on sales, named it best whole home backup (July 2026) after drawing 2,645.91 Wh, 86.1 percent of rated, charging it fully in 2 hours 20 minutes and running a test fridge for 28.97 hours, and faulted its 37.81 percent overhead loss in that test.
- TheSolarLab, which earns affiliate commission and carries Anker discount codes, measured about 84 percent inverter efficiency and 20.5 W of idle draw, found it near silent under heavy load and faulted cramped AC outlets, a proprietary charging plug and split solar inputs.

OUPES Mega 3

What they say
Anker SOLIX F3000
- Home Depot's five Anker SOLIX station files hold 269 reviews, and setting aside 115 marked as customer reviews from Anker and 17 from its Reviewer Program leaves 137 native reviews from 2024 to 2026, 53 of them ratings without text.
- Native owners describe running refrigerators for 8.8 to 32 hours, CPAP machines and a well pump, and praise fast recharging, while complaints gather on the F3800, with failed solar or DC inputs, a display failing after a year and a shutdown at about 1,800 W of UPS load.
- Lowe's shared C1000X Gen 2 and C2000X Gen 2 file holds eight native reviews among 40.
- Best Buy's 96 C1000X and C1000X Gen 2 reviews all carry the Incentivized or Tech Insider Network tag, and Walmart's 66 C1000X-series reviews and most of Sam's Club's are syndicated from Anker or incentivised, so they are not counted.
OUPES Mega 3
- No US retailer lists the Mega 3 with a review: Walmart's Mega 3 listings are gone, and Lowe's Mega 3 page carries no reviews.
- This reads the Mega 1 and Mega 1 Lite file on Walmart (item 11344470227), sold by OUPES's own store, which shares the Mega series app and B2 expansion battery with the Mega 1: 4.3 from 136 ratings, 4.3 from 132 with Walmart's four incentivized reviews set aside.
- Owners praise the fast wall charge and overnight refrigerator runtime, against units that died after a full discharge and app dropouts.
