It's fast portable easy to use fast charging

Dead simple charging

It was extremely easy to top up the charge and it jump started my SUV at a professional grade level.

It holds a charge while on storage as well.

Easy to set up and versatile options as a charging for portable devices

After getting my car started, I went to Auto Zone and since the battery had charged and was working, they told me they would not honor the warranty on the battery.

Fantastic! comes charged at 85% out the box, still requires full charge after but has all you need to get going for charging accessories and jump starting

Liked that it arrived early and it was ready to use since it was already charged to 85 percent

so at 50 % battery power life it worked like it was 100 % charged up, and after that use, it was at 47%

Not sure how it works on cars, it’s been over a decade since a dead car battery, but my riding mower battery when cold doesn’t hold enough charge for three weeks in the fall, and a gas generator I had sitting for over a year was not charged to start

Quick set up and battery came with enough charge to jump my car

Holds a good charge, and lasts a long time

It's leveling out the battery pack with the deficient charge in the car battery, and it's clicking while it does this.

It's very nice and fast charge, I like this product

I like the fast charge capability and the 12 volt car adapter attachment

Comes with a nice case and fast charging cord.

Charges quick, very convenient, works great on my F-150, charges phone fast charging

I set the electric charger on fast charge

Worked perfectly, was able to jump start a battery 3 times in a row and still had enough charge for a few more

have already started 5 vehicles on single charge-great product

Love it other portable charges won't start my car but this one does.

This jumper just works, and has enough charge to last multiple jumps if necessary

This product has already jumped my car off 3 times without a charge wonderful device saves a lot of time and can help you from being stranded

Seems well constructed and holds a significant charge while being stored.

The charge was very low as well when it should have been full.

So easy to use keeps a good charge

Holds a charge for months no problem

Nice and compact charges up fast

The cables are a little short for a hybrid but you are able to connect the negative charge to the metal so it works.

After 3 months----pack would no longer ACCEPT a charge and just lay dead

Bought this as a just in case, It functions similar to its competitors however it does not provide ample charge to the battery to start an auto engine.
