HIGHLY RECOMMEND!
Excellent! I have trusted many versions of this device since 2017. Comes charged about 60%. I just jump started a 2001 Ford F-250 7.3L diesel engine with ease. That only used up 14%! This purchase was to upgrade my old unit that I use with my 2011 Camaro 6.2L. I also used my old device to charge my phone and tablets when charging. I’m looking forward to using the wireless charging of this iteration!

Nice compact design.
I use this jump pack in my shop for small engine work. It has performed well over the years I've had it, with no issues.

Ruined my laptop
Used an open USB port on my laptop to charge it, once I got in in the mail. The battery percentage started dropping on the jump starter, and my laptop shut off. Not to come on again. $2,000 Dell laptop. Not cool. Clearly defective.

Love this thing. Wish I would had it earlier
My battery gave out on my 2018 Escalade. I wish I would have this. I bought another one at a store but it didn't have enough power to get my vehicle started and I had a call. AAA. End up buying this afterwards and I love it. For all the features that has with the charger on top and the power it has to crank over even a diesel 8.7 l. Used it once. Hope I don't have to use it again but if I do I know it's going to be there for me. Definitely buy one of these again!

Schumacher SL1643
I ordered this after having to have my car jump started and the service man used a similar model.The first one I ordered did not work. A Schumacher tech walked through testing it with me and offered to send me a label so they could repair it. Instead, I returned it to Amazon and ordered another.Requires a 2A USB charger, but doesn't come with one. I used the charger for my iPhone.Came 88% charged and reached 100% relatively quickly.My iPhone max has been sitting on it charging for about an hour and has gone from 80% to 95% which has reduced the power level in the jump starter from 100% to 90%.We shall see how well it holds up to being in the trunk of my car.

Very Dependable, Keeps Strong Charge
I bought a similar jump pack a couple of years ago. (Different brand.) The last one would jump the car once and need recharged. THIS device has made me very happy. I used it 4 times without needing to charge it. Actually, it is still holding the charge. I'm not sure how many jumps I can get before needing to charge again. I will update this review if I have more data to share.
