I used this $60 jump starter in a real emergency, and it brought my car back to life
"The Alpha is like a big, pound and a half power bank that packs some serious battery power, modest dual 18W USB-A and USB-C outputs. It has the circuitry needed to amplify the power through the 12V cables to start 6.5L gas or 3.0L diesel engines about 25 times (a claim I didn't think I'd be able to test, but turned out I did). There's also a light on the front, a big display, a couple of buttons, and a couple of outputs."
"The ports are covered with rubber flaps that give the unit IP65-compatible water and dust resistance, but they are on tight and incredibly hard to remove. It has a super-fast 65W recharge feature that can take the Alpha from zero to 100% in 45 minutes. Also, the batteries are designed to operate at a wide temperature range: -4℉ to 113℉ -- and can hold charge for a couple of years."
"It was to be a near-thousand-mile round trip with some friends to the town of St. Ives, on the southwest coast of England. We were traveling down in multiple vehicles, and I threw the Hulkman into my friend's car as one of those "just in case" things. Well, as it turns out, I was glad I did -- because it saved the day."
The Hulkman Alpha 1,000A/37Wh functions as a 1.5-pound power bank with dual 18W USB-A and USB-C outputs, a front light, large display, buttons, and dedicated 12V jump-start outputs. The unit's circuitry can start 6.5L gasoline or 3.0L diesel engines about 25 times. Ports are sealed by tight rubber flaps providing IP65-like water and dust resistance. The battery supports -4℉ to 113℉ operation, holds charge for years, and recharges from zero to full in 45 minutes via 65W input. The device proved effective during a near-1,000-mile trip by restarting a friend's Volvo that refused to start.
