This worked well the first few times I used it. Now, Im not sure if it will hold a charge. Ive had it for a while though and need to cycle it a few times to try and get it recharged.

The claim:

❤JUMP STARTER CAR LIFE SAVER£º400 amps of peak current, heavy-duty clamps and cables help jump-start your vehicle up to 10 times(up to 4.0L gas or 2.5L diesel engine).

My view: Yep... I can confirm that it works for about 8 times. A buddy had a car with a dead battery and I lent it to him til he could get a new one. Worked like a charm each time. 

The claim:

❤SMART CHARGING PORT: 8000mAh capacity and dual smart USB port: 5V 2A input port can fully charge the car battery jump starter at about 4H;15V 1A input port can fully charge your car starter power at about 3H. Besides, with QC 2.0 output port, charge your smartphones, tablets, and other devices at the fastest speed possible.

My view: it does seem to charge fast when first using and charges other things with relative speed. After a while setting though, it doesn't seem to want to charge. Perhaps one should charge it every so often to maintain the ability?

The claim:


❤DESIGN COMPACT AND ELEGANT: With a compact size and 380 gramme, it's easier and convenient for you to carry whererever you will go and store in your glovebox. With the character of waterproof, drop resistance and LED indicator.

My view: Besides the bad English here... it is lightweight and does fit in a glovebox. 


The claim:


MULTIFUNCTIONAL LED TORCH: with 3 light modes, including SOS and emergency strobe light.

My view:  yep. light works just fine



The claim:

❤WHAT YOU GET: Keenstone Jump Starter, Jump Cable Clamp, USB Charge Cable, 12V Car Charger, Portable Compressive Case (Gift), Manuel, 18 Months Warranty and 24H Customer Service.

My view: I haven't used the warranty yet, nor the customer serive, but the items they claim are shipped are. Even if the manual is in confusing english. 

Price: $43.99
