I bought one of those in March along with a Everstart 400w inverter to charge it back up when driving my car. Worked swell until September when the jump start feature stopped working. Button was intact but the screen stayed blank when the cables were connected. If I connected the cables after the engine started, the screen would light up showing the cable icons and the jumper battery level of charge. Walmart wouldn't do an exchange or refund since 90 days had passed. I called Everstart customer service where an older American woman said I screwed up the battery by using an 110v inverter to charge it. Told her that the battery was fine and the problem was with the internal circuit board. She said I ship it to them for testing but would need to pay the postage both ways, which was $90. Asked if they can repair the circuit boards there only to be told they'll only test the battery. I hung up and began draining the battery down to 7.5v a few times between charging back up to 14v. Did that 3 times and now the screen lights up to show the charge when pressing the jump start button. Still doesn't show the cable icons nor will the jump feature work. I've been charging it while showing a full charge of 12.8v since it'll rise up to 13.2v within a minute and get up to 14v after 15 to 20 minutes. Plan to keep that up it reaches 40 hours of charge time (have logged 17 so far). Am curious to see if that brings up the CCA level the circuitry requires to kick on the jump start feature. If it doesn't, then I'll figure out how to bypass the button to have constant power to the cables. Wish I could obtain the circuit diagram for this thing.
I have the same one and it doesn’t charge , I change the power adapter and only the screen flashes but doesn’t show the charge level , what can I check…? Thanks…👍👍👍
Unfortunately, this got left out in the rain. We dried it out but now it won't turn off. It appears that everything else works fine. I couldn't find a reset button. Any suggestions?
I have the same model. When attempting to use the AC inverter, I'm seeing a "fault icon" on the screen. I can't find anything on the internet to help me diagnose what might be wrong. Purchased at Walmart, not sure who to contact. Any advice?
In instructions it just says to unplug and plug back in. What are you trying to run? It may be too much power for it. You can try it on a lamp. If still does not work I would exchange it at Walmart.
Several guys are having same issue mine has. Charges up, let it sit and after a few days to a week it’s lost enough juice to not function. Has anyone fixed this and have advice? Thanks
It's a "SEL" brand vrla/sla battery, 19ah which is rated 240ca, not cca! So the advertised 600a instantly and the 1200a peaks is a complete lie. They also come heavily sulfated with high resistance. It is impossible to get a good jumper, I've bought & returned about 4 of these from Wally's world and tested them all with a digital battery tester and a 150a load tester, they are ALL bad!! They ALL have old batteries in them. I can see the date codes on the batteries and they are several years old.
@@jdsfsdfshdgdfhdfsgh I may as well just stick a battery into a box so it can be carried. I have used an inc jump box (the jnc600) that actually worked pretty well but carrying a battery should work just as well.
Good video fixed mine also took out air compressor nylon gear stripped out in hub first use
Have you repaired one that doesn't take a charge anymore?

How do you charge this battery charger? Lost the booklet.
Hola. La función de inversor no enciende y no carga varias. Que puedo hacer?

I’m looking for an air compressor replacement/repair video for one of these.
My cooling fan won't cut off
Mine wont hold a charge how do it fix it? And is there a way to turn it off i feel like i always waited for it to turn off
make sure that the three arrow symbol in the right-hand corner is turned off, and then it will be able to automatically turn off again.

I'm still trying to discover what battery they chose for these, I don't want to spend a bunch of money on another underpowered weak jump box.

that button isnt working on mine. i see why people end up pushing them too hard.
can i overcharge this device? does it cut off automatically when its fully charged?
If working correctly should be ok to leave plugged in. That said I generally unplug mine once fully charged.
@@PRIMORR thanks
I'm just trying to fix this error in front of my car and this is a 21 minute video?! Ridiculous.
This is a trash product. The buttons fall off and the light gets stuck on and won’t turn off
Mine done the same thing man
Easily the worst brand to ever exist.
