- Can it start a completely dead battery?
- Yes, the Boost button is designed to force a jump on batteries reading under 2 volts. That covers cases where a standard jump starter would refuse to output.
- What engines can it handle?
- The rating is 1,500 amps peak for gasoline engines up to 7.0 liters and diesel up to 4.5 liters. Cold weather and a weak battery reduce the margin, so leave headroom for big diesel trucks.
- How does the air compressor work?
- Set a target pressure in PSI, KPA, BAR or KG/CM2 and pick one of four modes, and it stops at the preset. The hose and four adapters cover car and bike tires, balls and similar inflatables.
- Can I charge my phone with it?
- Yes. The 16,000-mAh battery has dual USB outlets, one with 18-watt quick charging, so it doubles as a power bank between jumps.
- What comes in the box?
- The unit, heavy-duty jumper cables, a 1.31-ft inflation hose, four inflation adapters, a USB-C to USB-A charging cable, a carry case and a manual.
- How is it different from a jump starter without a compressor?
- It adds tire inflation and USB charging, so you carry one device instead of a jump pack and a separate pump. The trade-off is more weight and size.
