OSCAL PowerMax 3600 Portable Power Station
The OSCAL PowerMax 3600 is a rugged 3,600 Wh LiFePO4 portable power station. The US-standard version delivers 3,000 W of pure sine wave AC power from four outlets, plus USB-A, USB-C 100 W, 12 V car, DC5521 and Anderson outputs. Capacity expands to 57.6 kWh with up to fifteen BP3600 packs, so it scales from camping to whole-home backup.
Built on OSCAL’s rugged-phone heritage, the housing is UL94V-0 fire-retardant, anti-UV and drop-tested to 0.8 m. It recharges from the wall at up to 1,800 W (US standard), from up to 1,600 W of solar, or from a vehicle, and the 5-8 ms UPS switchover keeps sensitive loads running. OSCAL backs it with a 5-year warranty. CSE Solar USA is an authorized OSCAL distributor.
