I was really surprised how long the charge lasts charging my cellphone and stuff. i haven't started a vehicle yet , but it seems to be heavy for its size and looks like it's built well. the option to get the charging block is a better deal, its like 10 bucks more, but its a 65 watt fast charger and definitely charges the jump starter quickly and my s24 cellphone. definitely pay the extra for it.

Great deal!

Walmart shipped ASAP which was super! The charger was well packed. Charged up to full charge in minutes. Directions easy to follow. Most importantly, charged my car instantly. Engine roared back to life with the turn of the key and still left 96% charge left. This elderly citizen is a big fan now.

AS ADVERTISED AND EVEN BETTER

was using a conventional booster charger with an AC compressor in weather under 40° degrees on my old exterior. In weather under 30° degrees that wouldn't even even start it. But this does first time every time. well worth the money and it is not that expensive compared to other boosters.
