I was so impressed with this that I immediately bought another unit for a family member. The tire inflator pump is loud, but that is to be expected, after all, it has to mechanically function somehow, right? Works as described, both as an emergency charger and an inflator. Holds charge over time without drop in power, in my experience, but the reserve capacity is not overly generous (but is adequate) and for piece of mind id used as an emergency tool, should be kept fully charged. Also, purchased it when it had a temporary price reduction, so got lucky. Good value. Certainly beats calling a tow truck or waiting for someone else to help you out of a spot.

So far, I love this product!

I’ve had other separate Astro AI inflators and chargers before and they always worked great so I thought I’d give this combo unit a try. I had to inflate a tire today (car tire had a screw in it, had to plug it). It took 10 minutes 41 seconds to inflate from 5psi to 33psi and it dropped the battery from 100% to 63%. It was approximately 20°F outside (South Central Ohio in February) and I did have to bring it inside to warm up before it would inflate. I keep it stored under the back seat of my truck. The “Low Battery Temperature” light came on so it wouldn’t operate. The owners manual does state that operating temperature is -4°F to 122°F so I was a little frustrated by that but it still worked well once I took it in the house for about 7-8 minutes. I don’t think that’s bad at all for a compact, light, portable, sub $50 (on sale!!!) inflator/jumper. Can’t give it a full 5 stars because of the temperature issue but I would still recommend it, just making sure that people fully know that it might need to be warmed up prior to use in very cold temperatures.

I’ve had it for nearly a couple of years (I like to get to know a product before I review it), and it does all those things very well. I had a very nearly dead battery (no lights) and it started immediately. The only deficit I’ve seen is that the display is somewhat hard to see in bright light. But the good qualities far outweigh that.

I purchased this portable battery charger Jan, 23, 2023, but today was the first time I had to use it. My sister’s car broke down up the street from my house. She had called AAA, and they told her it would be a three hour wait. I remembered I had this and walked to her car. I followed the directions,(super easy, with pictures)and the car immediately turned on, but went off after a couple of seconds. I repeated the process, and it started again, but it turned off a couple of seconds later. We’ll, I also had purchased a HALO which is supposed to do the same thing, nothing happened when I used it. My sister comes out of the car and tells me, “Well, it did start it, give it more juice. I said, it starts it, but the car goes off after a couple of seconds.” She says,’ No, I turned it off both times.” OK! Yeah, don’t do that. Anyway, long story short, I jumped her again, and it worked. I had my reservation about this, but I promise you, if you are looking to purchase this, please do so. I was not paid to promote this item. I paid full price, and my review is an honest one.

I’ve been using this jump starter with an air compressor for a while now, and it has been fantastic. I’ve used it three times to jumpstart two vehicles, and it works like a charm every time. It also does a great job inflating tires, and I’ve used it several times for that. One thing to keep in mind is that you’ll need to charge it after each use—I’ve noticed it drops about 15-20% of its battery after use. To be safe, I always make sure it has at least 75% battery life before attempting to jumpstart a vehicle. Overall, it’s an excellent tool to have on hand for emergencies, and I highly recommend it!

I have a 3/7L V6 and the key got left on over night, the jump starter had 99% battery power when I turned it on and it couldn’t start the truck engine. The battery on the truck wasnt comptely dead either, it had enough power to luminate all the lights and could start turning the cold engine over.

I haven’t used the jump starter on this yet BUT this thing is a tank. It is a decent weight but it’s built strong. Got it and charged it and then pumped up tires for 3 cars and didn’t break a sweat. It seems pretty accurate when I compared it with my other tire gauge. Instructions are straight forward and the storage is cool on this machine. Easy to use and you should get one!

Absoute garbage. Can’t hold a charge, always dead when I do need it. Even when charged, it never has successfully jump started my car. Don’t waste your money

Es bastante portátil y tiene la posibilidad de inflar pelotas, ruedas de moto, ruedas de bicicleta y ruedas de auto, con pre seteos para cada uno de estos elementos, también trae una pequeña luz que a mi opinión no tiene mucho sentido pero puede cumplir la función de alumbrar el pico de la rueda del auto si estamos en algún lugar totalmente oscuro, eventualmente se puede usar como powerbank por el puerto usb pero a mi no me ha dado mucho resultado cargar el teléfono con el, pero también, eventualmente puede salvarte unos minutos de carga.
