I’ve had this sitting around for about 5 months in my truck, it didn’t lose any charge turning that

Tried charging over night and it just blinks rapidly and never gains charge

The battery seems to hold its charge well so far, though I've only had it for a few months

It even comes in handy charging my Iphone in an emergency

It keeps a charge pretty well and recharges itself quickly from the car lighter or my campmates' c-pap generator.

After using this Tacklife to "Jump" the battery it must have given enough charge to the cells to allow it to take a small charge for the subsequent build-up using the trickle chargers because I checked it this morning and the battery is now at over 12 volts and rising

One other great thing that I really like is how well this device holds a charge even after jumping a car 25 times it still has 2 bars short of full power which is impressive considering how many things requiring charging daily if not multiple times a day (looking at you smart phones, wearables, etc).I can't recommend this highly enough to literally everyone.

I've used this to jump start cars a few times as well as charge electronics.

have one in all 4 of my vehicles.im amazed how long it keeps a 100 % charge well over 6 monthes.

I had issue with my product charger was not charging I emailed customer service replacement sent right away

After 3 months of use don’t hold the charge any more not recommended

So far this thing is awesome... haven’t needed it in a pinch yet but worked great charging our phones multiple times!

Small handy and charges quickly.

This wouldn't even hold a long enough charge for my phone to replenish once

Worked very well, started my silverado truck with ease in seconds, and had good auxiliary charging capabilities for phones, and such

This thing is a lifesaver!It's incredibly easy to use, contains handy charging cords, and holds a charge in the cold

I’ve jumped my truck off with fully charged 6 or 8 times and still had an enough charge to do more

Theres a few extra tools added to aid you with checking tire pressure and the battery itself provides fast charging if your out in the battery boost it also provides the cable as well

And, to make it better, once charged, you can pack away in the car and not worry about it running out of power after 6 to 12 months

went to use it for the first time, had no charge, would not charge, 100% junk.

It's incredibly easy to use, once charged.

It worked perfectly and still has a good charge left

The device indicated the SUV battery did not have sufficient charge to start with device in normal mode.

The weird part is that it holds enough charge to do that over and over, many jumps.

So far so good it was 80% charged

Fortunately she had everything hooked up and there was enough charge to get here started

It's very easy to use, and the charge seems to last for months, so it's great to keep in the car for peace of mind

I used it only onece and it worked as it was supposed to.

It worked exactly as it is supposed to.

Works as it should be
