Car Battery Booster Portable Jump Start Starter Charger

All I can say is wow, this tiny lithium jump starter got what thought was a dead as a doornail car battery back to life

A third party charger isn't able to take this battery from zero to usable, so make sure you jump-start it using the official Leica charger.

Works great. The official charger was the only one able to jump start the battery though, but after the initial little bit, I was able to confirm that it charged more than 1800mAh.

Other than a jack, this compact jump starter is the number one item every car should have in it. Completely discharged my battery overnight, hot the"boost" and the car turned over immediately.

Originally bought my Watson portable car charger for my Nikon D5300 battery. Didn't realize that the plates were interchangeable, so when I upgraded to my new D810, I figured I would need to buy a whole new charger. But no...just a new adapter plate and I was all set. Great product!

This is a nice compact battery booster. It will start most vehicles that haven't completed depleted their battery. My old start boost device had basically died. It wouldn't hold a charge despite being plugged in. This new booster works perfectly.

Excellent quality… Love it! . Well use it to charge jump starter.

Installed this replacement battery in a Schumacher XP2260 Jump Start. After turning on the XP2260, it displayed a full charge of 100% without any further charging necessary.

At first, before reading the directions, I was disappointed that the jump pack could not turn over my car. Dead battery and all. However, after understanding the directions for use on a DEAD battery the pack brought engine to life better than a brand new battery ever had. Pricy, but worth it.
