ASPERX 3000A Jump Starter for Car Battery 12V Portable Jump Box with LED Light Smart Jumper Cables BMS

So far so good. This little jump starter saved me a few times! I hope it lasts but for now it worked well and seems well made. It fits in the glove compartment and can be charged in the car so that's also very helpful. I don't have to wait for road assistance to arrive with their similar machine whenever we're stranded due to a failing battery. Read more

I have had this product for a while but haven’t had a chance to use it till today. My jeep battery clicked when I try to start it. This booster got me up and running. It paid for itself first use. Very pleased Read more

I bought this for my son's car (2018 Subaru Impreza) for Christmas. On Dec 22nd, he had inadvertently left his interior lights on overnight and was unable to start his car. So, happy early Christmas present! We broke open the gift early and it allowed him to start his car... happy day and way easier than using jumper cables to my car. Read more

I purchased this item because I unintentionally kept letting my battery drain and had to jump start the car every day. When I realized what I was doing, I corrected the problem and replaced the battery. The battery charger did what it was supposed to do. I was really happy that I had it because I was able to charge a car by myself without the assistance of another person or plugging up to another car. I’m not very handy so this was perfect for me. My only issue and rating of four stars, was that the battery charger had to be fully charged or it wouldn’t jump my car. For example, when the battery charger was half charged, it would not jump my car. The other issue is that it takes about four hours for the battery charger to be completely charged. Since I purchased a new battery, I no longer needed it. However, I kept it in case of emergencies or to assist another person that might have a battery issue. It’s always good to have one handy.

FANTASTIC, Best buy ever. I have an 88 year old car with a 6 volt system. It is very hard starting, even with the battery charged. I found the battery was completely dead and figured it would be a good test for this jump box. I followed the instructions (boost) for a dead battery. I ground on that starter longer than any 6 volt would have lasted. Just as I was about to give up, the engine started to try to start. Then the engine took off. This jump box has my full approval. I immediately ordered a second one for my other old car. Read more

This works excellent, I would recommend it in a heartbeat. I've had it for 3-5 years and never had a problem i don't really use it but stays change at 90 something % whenever I pick it up. Read more

I'm always leery of made in china junk. But with the extra 20% coupon and the 74% 5 star rating, I took a chance. There are other similar china made units that had 1000A & 2000A peak current ratings, this has 3000, another reason I took chance on this one. I had a dead car sitting for 2 months. Even electric locks would not move. I attached unit, nothing. Then I pushed the Boost button (on part that cables come out of). It triggered my car alarm, after composing myself, I started the car right up. I only moved car off the driveway. Next day car was dead again, or still dead. I used the unit second time, same results. This time drove the car long enough to charge. Battery has 37Wh rating. If I do my math correctly, for a 5V device that's about 7Ah, or 7000mAh, which is a pretty good backup battery for phone type devices. If it doesn't last I'll update the review. Some 1 stars said company didn't honor their 18 month warrantee, I hope that's not true. ---- 4/23/25 I have 2 extra cars not getting driven enough. Have had to use this 12 times in past few months. It's been a lifesaver with the street sweeper bearing down on me. After 6 uses with the high boost button, the blue bar charge status went from 4 to 2 bars. Price dropped to 40 bucks, I'm here buying Christmas presents, so figured I'd update review. Flashlight has blinking options which is nice safety feature if stuck on roadside at night. Read more

I love this battery charger Read more
