ALLWEI power station review: specs, warranty and safety claims for the 300W, 500W and 2400W, and how each compares with Jackery, Anker and EcoFlow.

GRECELL power station review: the $500 2400W (1,843Wh LiFePO4) is the pick; the 1000W, 500W and 330W use NMC and charge slowly. Specs and math.

Most reliable solar generator brands: BLUETTI, Anker SOLIX and EcoFlow lead on 5-year warranties and CPSC recall records. Jackery, Goal Zero compared.

DJI Power 1000 V2 review: 1,024Wh LFP, 2,600W, 80% in 37 minutes, but only third-party sellers on Amazon US, from $420 to $699 since September.

Goal Zero Yeti 1500 (6th gen): 1505Wh LiFePO4, 2000W/3600W surge, 900W solar, 1.1-hour charge, IPX4, about $1,500. Specs, runtimes, rivals.

Solar generator maintenance: store at 50% to 80% charge, keep it under about 104°F, don't leave it empty, update firmware and test capacity yearly.

Solar generator in cold weather: it runs below freezing but won't charge under 32°F without a battery heater. Plan on about 80% capacity in winter.

Jackery Explorer 1500 v2 review: 1,536Wh LiFePO4, 2,000W, about 32 lb, $849 at Jackery (off Amazon US). How it compares with the 1500 Ultra.

Semi-solid state battery vs LiFePO4: up to 42% more energy per pound (Zendure's claim) but 3,000+ vs 6,000+ rated cycles. LiFePO4 is still the pick.

LiFePO4 vs NMC battery: LiFePO4 is rated 3,000 to 6,000 cycles vs about 500 for older NMC units and is safer. NMC's only edge is lighter weight.
