I bought this for my son's car (2018 Subaru Impreza) for Christmas. On Dec 22nd, he had inadvertently left his interior lights on overnight and was unable to start his car. So, happy early Christmas present! We broke open the gift early and it allowed him to start his car... happy day and way easier than using jumper cables to my car.

This works excellent, I would recommend it in a heartbeat. I've had it for 3-5 years and never had a problem i don't really use it but stays change at 90 something % whenever I pick it up.

Works well only issue is not for someone who has gripping and squeezing issues to attach to car battery. The connector cords are a bit short so keep is really close to the battery.

Works great, hooked to dead tractor battery, boost, and turned over right away.

FANTASTIC, Best buy ever. I have an 88 year old car with a 6 volt system. It is very hard starting, even with the battery charged. I found the battery was completely dead and figured it would be a good test for this jump box. I followed the instructions (boost) for a dead battery. I ground on that starter longer than any 6 volt would have lasted. Just as I was about to give up, the engine started to try to start. Then the engine took off. This jump box has my full approval. I immediately ordered a second one for my other old car.

I'm always leery of made in china junk. But with the extra 20% coupon and the 74% 5 star rating, I took a chance. There are other similar china made units that had 1000A & 2000A peak current ratings, this has 3000, another reason I took chance on this one. I had a dead car sitting for 2 months. Even electric locks would not move. I attached unit, nothing. Then I pushed the Boost button (on part that cables come out of). It triggered my car alarm, after composing myself, I started the car right up. I only moved car off the driveway. Next day car was dead again, or still dead. I used the unit second time, same results. This time drove the car long enough to charge. Battery has 37Wh rating. If I do my math correctly, for a 5V device that's about 7Ah, or 7000mAh, which is a pretty good backup battery for phone type devices. If it doesn't last I'll update the review. Some 1 stars said company didn't honor their 18 month warrantee, I hope that's not true. ---- 4/23/25 I have 2 extra cars not getting driven enough. Have had to use this 12 times in past few months. It's been a lifesaver with the street sweeper bearing down on me. After 6 uses with the high boost button, the blue bar charge status went from 4 to 2 bars. Price dropped to 40 bucks, I'm here buying Christmas presents, so figured I'd update review. Flashlight has blinking options which is nice safety feature if stuck on roadside at night.

It works great.

Excellent piece of kit. Was dubious at first, as it is a very small machine, but worked perfectly. Easy to use, compact with storage case. Rechargeable with USB ports.

Muy buen producto funciona muy bien

Schnell geladen und funktioniert einwandfrei

El equipo viene bien protegido, con funda y carcasa para proteger contra golpes. Las pinzas se ven de buena calidad. Ayer lo probé y arrancó de inmediato mi Jeep. A gusto con la compra.

Hoffe ich brauch es nicht, bzw. kann ich damit vielleicht anderen Leuten helfen mit leerer Batterien. Benutz hab ich es bis jetzt noch nicht, aber für denn Notfall brauchbar mit denn Funktionen
