ALLPOWERS R1500
#21 in Mid-sizeFull review
A low-cost expandable LiFePO4 station for home backup at moderate loads. Testing suggests it struggles near its rated 1,800W, so keep heavy loads well below that.
ALLPOWERS $539$539
The ALLPOWERS R1500 and the Dabbsson DBS1300 are evenly matched, rated 4.1 and 4.0. The ALLPOWERS R1500 leads on AC output and solar input. The Dabbsson DBS1300 wins on portability. The ALLPOWERS R1500 costs $60 less ($539 vs $599).
Dabbsson DBS1300
#26 in Mid-sizeFull review
For campers and small-household backup buyers who want more than 1 kWh at a modest price and the option to add batteries. Its 1200W output limits it to everyday devices rather than big appliances.
