HULKMAN Alpha85 Jump Starter — 2000A Portable Car Battery Booster for 8.5L Gas & 6.0L Diesel
The HULKMAN Alpha85 is the kind of thing that sits in your trunk doing nothing until the morning your car won’t turn over. It delivers 2000 amps of peak current, enough to start gas engines up to 8.5L and diesel engines up to 6.0L, and the 20000mAh (74Wh) lithium pack is rated for roughly 60 jump starts per charge. A 3.3-inch display shows battery level, operating status, and error codes, so you’re not guessing whether you clamped it correctly. It recharges at 65W — 0 to 80% in about an hour — holds a charge up to 18 months, and doubles as a USB power bank.
