   I’m pleased to say, they reached out to me and sent another unit. I waited 2 weeks to respond. The new unit is still charged, so I am delighted. It was important because of the dual function of jump starting and tire inflation. They trusted me enough and didn’t want the old unit back. It indeed the old unit didn’t keep a charge. Thanks again AVPOW your customer service rocks. Here is your deserved 5 stars.

   I ordered the AVAPOW Car Battery Jump Starter 4000A on 12-2-2024 from ezysurvival.com. After charging the unit, as explained in the directions, I used the AVAPOW 4000A 3 or 4 times to inflate tires as needed.

   The last time I tried to inflate one tire, the AVAPOW 4000A unexpectedly shut off and would not restart.

   AVAPOW – responded very quickly and replaced my AVAPOW 4000A. The new unit works as expected so I raised my review.

   UPDATE: I was contacted by the manufacturer and a replacement item was sent out to replace the one I received. It was relayed to me that what I received was not indicative of what we as consumers should expect and their efforts showed that they take pride and are willing to correct problems with their product. The product received works flawlessly. Original post: I like this multipurpose unit. It came partially charged and I used a USB charger to top it off. It provided a sufficient boost to start my daughter’s car. I like the built-in light with this device and it gives off enough to be functional while working on a vehicle or just at night. The one thing I did not like about this item was that I could not use the air compressor portion. Why? The port to screw the hose int the machine was out of alignment that the hose would not screw into the treaded portion to use the air. Also, there was a crack near the port for it (see pictures.) The manufacturer should pay closer attention to its’ quality control to ensure a viable product is delivered to the consumer.

   I used it to fill up the air in the truck tire. It looses air at the start of the fill. And it leaks.
   I need this to start a tractor (most of the time). But it’s just painful to get it to working. The steps to start are not user friendly. After too many efforts it worked.
   I was hoping this to be good. But alas. I returned it.

   Worked great and quick for airing up tire in the mountains.

   Also used on separate occasion for a car jump, worked quick and successfully

   Charges back up pretty quickly

   I’ve had it for about five months and it’s jump started and aired up everything I’ve thrown at it. Today I jumpstarted a 36 V semi truck, and earlier in the week I jumpstarted my lawnmower yet the battery has only dropped to 84%. Every time I’ve hooked it up to a dead battery it’s instantly ready to start.
   I’ve only used the air inflator once to air up a tire on a car hauler and it worked great. You can set the pressure and it will automatically shut off.
   Overall, I think it’s a good machine.

   The pump is really annoying to use on this unit. First it takes a lot of fiddling to screw the hose on – because the end does not rotate on its own, you have to awkwardly spin the entire hose to thread it in. So then you click the pump button, and the air units default to KPA, then you click units then it goes to BAR, then after another click it will go to 36 PSI. If you want to change the pressure, you then click some more. When you go to the fill next tire, you repeat this entire process because the unit defaults back to the jump starting mode pretty quickly and it doesn’t remember any of the pump settings you just entered. It’s a shame as the pump itself is decently fast and quiet. And the power functions seem decent too with 65w USB-C charging. It seems like a pretty good unit if you care mainly about jump starting and charging, but if you want to use the pump regularly, best to consider a different unit.
