[GOLD] 12V Portable Jump Starter with Built-In Air Compressor and Smart Safety Protection

The air pump heats up the pump pipe after adding 5 psi air into two tyres. Quite hot adding air in all 4 tyres.

Its been great so far. The only problem i have is that i cannot get it to stay at PSI. Everytime i power it up I need to change it to PSI and change the numbers to what I want. It looks like it resets and doesn’t want to stay programmed at what I set it up. Maybe I need to do something that its not explained in the instructions. Other than that its ok.

They gave charging cable very cheap and it’s not charging and gets too hot within 5 minutes,,,,, And they showed that car started 49 times with one charge but it’s false because it doesn’t start the car many times ,,, so it’s not 100% matching the description
