I bought that about a year ago. I have kept it in my car and charged and have used it on 1 jumpstart and a half dozen times for tires. I bring it in today to pump up some scooter tires and it won't turn on. Buttons do nothing. I plugged it in with the main charger and no change after a few hours so I tried the other charging methods. When I used a phone charger it actually came on and said that it was charging but after a few hours the moment I unplug it it says error 140 and 170 and it shows that it is almost dead. Naturally there is an error 130 and an error 150 in the handbook but no 140 and 170 is a temp thing. It mostly says error 140 though and I have nothing to go on some it's likely junk. I'm currently trying to charge it via the DC cig lighter outlet on my ecoflow and it says that it is charging but it said the same with the phone charger so I'm not optimistic. Found this vid looking for any info on err140 but no luck. Maybe better to stick with genuine brands.
