AVAPOW Car Battery Jump Starter 4000A Peak with Air Compressor, 12V 150PSI Portable Jumpstart with Force Start Function, Portable Starters for Up to 8L Gas 8L Diesel Engine, PD 60W Fast Charging

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.

First off, I normally do not post reviews for my purchases unless there is something really good about the product that I feel others might benefit from the product(s).This winter seems to have taken a toll on the battery for my 2009 Chevrolet HHR LT, with temperatures well below 0°F (at one point the wind chill had reached -30°F)! Just a FYI, the battery for 2009 Chevrolet HHR's are located in the rear of the vehicle inside the spare tire compartment, making it more difficult to easily reach than if it was under the hood in front in the engine compartment. This model vehicle has just two posts in front to facilitate jump starts.I have a trickle charger that I tried connecting to those two posts to try "exciting" my car's battery and although the charger showed me a green charged light, it seems that wasn't good enough to help me start my car!I decided that I needed a battery charger that also had a boost capability, prompting me to order this charger/booster. After reading the reviews, I decided to "take the plunge" so to speak, the features also played more than a small part in my decision, like the fact that I don't need another car to jump start my vehicle being a major factor.The other reviews seem disappointed in the plastic case of the device itself, well I don't intend to be banging it around and the lack of a metal case keeps the device from getting colder to the touch than a metal case would be.The digital readout shows me the charger/booster/tire inflator charge is a great plus, being able to disconnect the battery clamps is also a great plus (making the storage for it more compact), the zippered storage case having a separate storage for all of the cables and air hose is another great plus. All in all, the size of everything being under a foot square plus the light weight, makes storing this unit quite nice!Even if you do not ever *need* a battery charger/booster or even *need* a tire inflator for _your_ vehicle, this device is extremely handy to have nearby! I have had many people ask if I could help jump start their vehicle, with this device I won't even need to pop the hood on my car. Plus, it will be great to have it just on the off chance that I might need it (which I did thus winter). Although I have as yet to use, or even try out, the tire inflator this feature will definitely be great to have on hand. It did not take me more than appropriately 10 to 15 minutes to charge up the battery inside this charger/booster, it came already 88% charged.Another great plus is the price for an outstanding purchase! Before deciding on this particular device I had checked several other devices similar to this one, looking at not only the features and price but also the reviews. Other people's reviews play a large factor in my decisions to purchase anything I might need or want on Amazon or anywhere else!Do I recommend this charger/booster/tire inflator? MOST DEFINITELY! Buy it, I whole heartedly guarantee that you won't be disappointed!

I ordered the AVAPOW Car Battery Jump Starter 4000A on 12-2-2024 from Amazon. 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.

Awesome Deal and so far since I been using Avapow a couple years, their products been Awesome. I have jump start but wanted one with compressor/ tire inflation ability. Yes all in one, also other uses stated charging other items is aplus also 4000 Amp is Great.

Will start a tractor trailer or a Toyota Camry. The compressor topped off all 4 tires on a 4Runner. If kept in a trunk the frigid cold will affect the unit. Well worth the money

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 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.

This item will not charge. I tried different charging bricks, and it will not budge over 83%. I called customer service and they were no help, so had no choice but to return. My search for an item that can jump my car and fill my tires goes on.
