Love it!
Bought for the hubby on Christmas 2025. On Christmas we had flooding in our town so the power went out for FOUR days! This thing came fully charged out of the box. I charged my iPhone 4 times and hubby's 2 times. It was perfect and clearly a great meaningful gift.

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.
