Title: USED & DEFECTED
Review: The product was not shipped in a typical retail package. It was in a blank card board box. The cables had wear & tear on them. The device itself had 0 charge. After charging to 100% it was back to 0 in less than 24hrs and it wasn’t even used. I would call this device defective.I would return but unfortunately my wifehad already thrown a way the packaging so I assume it can’t be shipped back. I want BUYERS TO BE AWARE! This product was not as advertised.

Title: Schumacher SL1643
Review: 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.

Title: Love this thing. Wish I would had it earlier
Review: 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!

Title: Works great. Handy wireless phone charger
Review: Already used it to jump off a car. Love the phone charger. This is the exact same unit as a Duralast branded model I got at Autozone but much cheaper.

Title: Works great
Review: It keeps it’s charge great and has always been ready to jump the work van, wife’s car, portable equipment at work. It’s never let me down even after 10 jump attempts trying to jump a battery that was far too dead to be possible even with a very powerful rolling jump box. Don’t bother using it as a battery pack for charging devices unless it’s a last resort but for it’s intended purpose of a jump pack it’s been awesome.
