BLUETTI FridgePower Portable Power Station, 2016Wh 1800W

- 2016Wh (expandable to 8064Wh), 1800W
- 75mm ultra-slim, fits 99.65% of kitchen gaps
- 4W standby, 26% longer documented runtime
Our take
An ultra-slim 75mm design fits 99.65% of kitchen gaps, mounting behind the fridge, on a wall, or in a side cabinet with zero floor space lost, DIY-mountable in 5 minutes.
Why it made the shortlist
This is purpose-built specifically for refrigerator backup rather than general use, with an ultra-low 4W standby draw delivering a documented 26% longer runtime (about 4.5 hours more) than competitors at the same capacity. Expansion to 8064Wh with BlueCell 200 batteries keeps a fridge running up to 4 days during extended outages.
DualGuard UPS switches in 10ms with four intelligent modes (Standard, PV Priority, Time of Use, Customized), and Storm Alert push notifications plus Alexa and Google Home voice control let you check battery status hands-free.
What works
- 75mm ultra-slim design genuinely fits behind or beside a fridge
- 4W standby draw delivers a documented 26% longer real runtime
- Works with Alexa and Google Home for hands-free status checks
Watch out for
- Purpose-built for fridge backup, less flexible for general use
- Full 8064Wh expansion requires separately purchased battery packs
