The Schumacher SJ1427 is a 6-in-1 portable power station built around a 1500-amp jump starter for 12V vehicles, rated to start 8.0L gas and 4.5L diesel engines. It adds a 200W continuous (400W peak) AC inverter with two 120V outlets, 12V DC and USB charging ports, a 150-PSI air compressor with analog gauge plus a separate high-volume inflator/deflator, and an LED area light with a digital battery display. It suits drivers of cars, SUVs and trucks who want jump-starting, tire inflation and small-device power in one unit. It is heavier and bulkier than a pocket lithium jump pack, and some owners report less starting power than the rating suggests.

Buyers call it a reliable jump starter that also inflates tires and powers small devices, and many would recommend it. The main complaints are weaker-than-claimed starting power and units that stop charging or holding a charge.
