AC DC Adapter Charger for Peak Stanley FATMAX 700 Peak 350 AMP J7CSR J7CS Jump Starter, Replacement Adapter Fit for Peak 300 450 600 700 Amp, for Jump Starter Portable Power Station

Worked perfectly for my peak jump starter 600 battery. I ordered a couple other ones before this but they weren’t the correct output. This one fits perfect and charged up immediately.

This does not charge a 700 Stanley. I’ve had it plugged in since last night and here it is almost 10am and nothing. I will be returning it asap.

Works good

This charger is a perfect replacement for the original that I lost. Charger the booster pack perfectly. I would definitely recommend this charger if yours has stopped working or you have lost your OEM charger.

a simple device.. works as it should. I would buy again if need.

I tried this when I could not find the proper adapter for my Stanley Fatmax 700. This is not the proper adapter and will not work properly. I tried charging and it never turned green for full charge. I was cleaning days later and found the proper adapter. I charged with the proper adapter and it turned green. Come to find out this adapter is not the proper volt. I think the real one is 7.5v and this is 13.5. The only thing that is right is the connector size.

Neighbor threw his old Stanley FATMAX 700 Peak Battery Jumper Pack away. Needed a charger, works perfectly!

I bought this for my "peak portable power system 700", but when I tried to plug-in on the device, it was loose and just didn't fit right. it did light up the charging light, but I was uncomfortable with the way it fit. The quality of it was very lightweight and cheap, but functional.

There was a bit of delay in getting the item. But it works as expected with Stanley Fatmax 750 without any issues.
