Solid chunky thing, I got one. It is like Theragun compared to no-names, you know why it costs twice as much when you hold it.
Close to lowest ever
CamelCamelCamel.
Have a GOOLOO 1500 that lost a fraction of a charge over 6 months and started my dying battery about 5 times today.. regardless of brand, these devices are awesome!
Nice… I got notified of this post cause you mentioned "Theragun"
lol
i dont know how these compare to a gooloo 4000 but these jumpstarters are really handy
used mine at least 30 or 40+ times since i got mine (starting project cars, local friends with dead batteries mostly)
also recently i had a coworker that couldnt afford to get his alternator fixed till next payday so he borrowed my gooloo and occy strapped it under the bonnet and used it to get him to and from work for a few days while charging it every night
also it can run a car fridge (engel) for about 5 hours, handy for when you go to your mates bbq and couldnt be buggered to constantly go in and out of the house to get another drink :)
my "thunderbolt"-branded jumpstarter came with a ciggy socket adapter so i could run two [ancient] dashcams in park mode for the whole work day
Any idea on the mAh?
1750000mAh
Btw I had Gooloo 2000, it discharged itself to death, killing LiPo cells. Returned for refund.
