I have 3 of their jump packs (keep one in each car) and one of them has just recently gone all puffy. It’s a few years old, used a few times.
The replacement I bought from gooloo and it was DOA, and they have been an absolute pain to deal with for warranty. They wanted to charge me 50pc of the price of a new one for warranty, had to repeatedly remind them that is not how warranty works. Now they’re refusing to send me a tax invoice for the original purchase (so I can go to consumer affairs) despite it being a legal requirement to send an invoice if a buyer asks for one.
So not impressed with gooloo at present ….
It's 3000A Peak not 4000A

Who knows how good the cells used in it though. Gooloo seem to use good quality lithium cells in their stuff.
