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

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'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've had to use this several times already for inflating tires and for jumpstarting. A couple of things stand out as a little annoying. First, you need to reset the pressure metric (psi, kpa, etc.) each time. Even when I inflated all 4 tires of my car, I had to reset to psi between each tire. Second, the case just barely fits the main unit. If you have the inflator hose attached, it will not fit in the case. So you have to detach and attach every time. If they have provided a little more space, you could just leave the hose attached. The user interface is not that easy. Fortunately, it is pasted on the unit itself. I still have to read it each time - you have to know to press something for "short" or "long" press, etc. to get to a particular function. The writing is impossible to read unless in direct light. It is just raised letters on black rubber. Wish they had added some color and contrast. So lots of functions and it works but usability could be improved.

Great jumper works great

Got this for my son who had small leak in tire from cracked wheel. Had to air tire up about every morning. Thought this would be great gift. Also the fact it's battery powered. Being a teenager he still can't figure out why cars die when keep radio, lights, doors open. I figured the instant jump start would come in handy.But unfortunately it held up for a month. It take a very long time to charge. Didn't stay charged long after taking 2 days of charging. It took around 20 mins or longer to air a small leak. The tube broke. Maybe good for in garage for little jobs and power bank. It did jump my car pretty fast so the was a perk

Great jump for cars, charging station in emergency. Be sure to purchase 60v charger (not included) for quickest recharging.

Got it with 66% charge. Charged to 99% in 3 hrs. Used it once and dropped to 97%.Initially was baffled... expected a wall plug but it charges from a 5V usb charger using a Type-A to Type-C USB cable. You supply the charger. I used my phone charger which is a fast charger.

It doesn't work, it's made or of cheap plastic.
