An item I carry now in all my cars
Great item. I bought this after the fact of needing it and still had the opportunity to use it in other situations. It definitely saved me time by not needing another person to come offer a jump. It goes without saying that it saves money.

There are other brands, don't buy this one
Could not get a full charge after two days of charging. Emailed the company several times and got NO response. Returned it.

Does what it is supposed to do!
This product does exactly what it is supposed to do. This is way easier than using traditional jumper cables and saves a ton of time. First time using it we had it charged up to 100%. It took about 10 seconds to jump the car we were trying to start which was awesome! I checked the battery meter right after and it had only dropped down to 98%. This is a game changer! I highly recommend this product to anyone that is tired of using traditional jumper cables and wants to save A LOT of time and headache!

Looks like a good purchase. 👍
Looks nice. Haven't had the need to use it yet. Hopefully it'll work properly and be a good purchase. I had a different brand and needed it a few weeks ago and pulled it out to find the lithium battery had leaked all over inside the carrying case. This new one also has 4 times the power. Only wish it came with a carrying case for storage, since it has multiple peices to keep togeather. Also it would protect the vehicle if the battery someday leaks.
