AsperX AX4500 Jump Starter, 4500A Peak Car Jump Starter for Up to All Gas and 10.0L Diesel Engines, 12V Battery Starter with 4 Inch LCD Display, Lithium Battery Booster with Built-in LED Light

This is an amazing product it does exactly what it says. I personally believe that everybody that drives a vehicle should always have a portable jump kit / battery flashlight and a tire inflator. This thing was powerful enough for me to plug in the car charge port adapter which is what my tire inflator runs on. I was able to fill two flat tires that had 6 psi in them while only bringing the battery down to 87%. I then hooked it up to my battery The light was blinking so I clicked the boost button like I said My car alarm went off immediately so I jumped into the driver seat twisted the key and it started up immediately from 100% dead. It is super easy and straightforward to use and probably the best value you can find for your money The light is also nice and bright.

Great for emergencies. It's not as strong as if you jumped a car cable to cable but it will do a quick jump to get you out of a bind. If anything you may have to jump the battery a few time by pressing the boost button. I love that it makes a sound when you have the cables in reverse as well as give you light signals. Has emergency light and flash light. Compact. Fits in the side pocket of the door if needed. Highly recommend.

I have used it to start everything from a lawnmower to a ford f350 and a dual battery diesel boom truck and it hasn't failed me.

Good

I had a completely dead car after I came back from a trip. I ordered this jumpstarter which came the next day and it started the car without a hiccup. It showed 95% charge left after the jumpstart. The unit looks nice. It is heavy. There was no charger that came with it. It did come with the usb-c charging cable though. You won't be able to charge it with a low wattage charger. Get a 25 watt or 45 watt charger, otherwise, you'll be charging it for days. I recommend this unit.

Better than expected works well

Realmente satisfecho con el producto

I remember when portable chargers for phones was not a thought in anyone's head but now it is just as important as the phone. Now it just a important that your car has one to. I tell everyone I know to get one & store it in your car no matter what. I got Asperx and gave it to my mother because it was so easy for her to use. Now I have buy another two more for myself. I recommend Asperx to anyone because the product does work. If you don't go with them, please just have some backup in your car. You never know what will happen.

I like others loved the product at first but after not using it for a few months it was dead and will not take a charge. I ordered this "Mar 16, 2025" it was stored decently though I do live in Canada so it would get cold but where else do you store it but in your car. It's currently about 18 months old, I'm not sure when it died. It's cheap and worked well but it's not reliable. reached out to support and they tell me they only support if ordered from them or something like that (had to translate it) I guess I'll try spending a little more on a reputable brand that might have better support. Might make a fun live target :)

Attractive, powerful, large display and easy to use. Be careful about storing the jump battery in a vehicle area that you may not have access to if your battery is fully dead (like the trunk). With a fully charged jump battery... - Connect the red cable to positive on the battery. - Connect the black cable to the vehicle's frame further away from the battery (contrary to the provided instructions, DO NOT connect to the negative battery terminal). - Jump battery display's GREEN light for ready. - Start your vehicle normally. Done!

My wife is 5'2", and sits close to the steering wheel. Soooo,,, when she gets out of my truck, her knee hits the light dial leaving the lights on for me to go leave for work only to have a dead battery. My neighbor had one of these and saved the day for me. So I bought one for the next time. Yes I still Love Her

Car fired right up, seems to be able to handle multiple boosts and has power supply for phones etc incase your vehicle dies and you need to charge a phone or somthing. Worth it to have have for a backup

SO FAR SO GOOD. I WON'T REALLY KNOW UNTIL I HAVE HAD A CHANCE TO USE IT OVER SEVERAL MONTHS. I HOPE IT WORKS AS ADVERTISED AND I WILL REVIEW IT AGAIN IN A FEW MONTHS.
