Update: just had it for 2 weeks or so, used it 3 times already and it still said 100% battery... i love it so far and works perfectly for the price I paid. Even though it said 100% battery I'm finally charging it because just in case of anything don't want it to die on me. I bought this because I got tired of taking my dad's portable jump starter because that one is heavy and pretty big... I saw this for $35 and I had to get it since it's basically the size of a power bank and every monday I have to use it since it somehow runs out of battery (since I don't use it the weekend) and this little guy I can have it hidden behind my seat and no one is gonna know it's there... I used this twice today and still has full battery and well will update if anything and let's see how long this lasts Read more

Powerbank yanında gelen aküye bağladığımız parça ile aracın aküsünü ilk olarak işleme başlamadan 8,5 V olarak ölçtüm. Kapılar kitlenmiyor, radyo , silecek vs çalışmıyordu. Akü o derece bitmiş. Cihazın önce kırmızı ucunu akünün + kutbuna , siyah ucunu ise - kutbuna bağladım. Powerbank’i “ on “ konumuna getirerek açtım. Kontağı çevirdim ,ilk denemede arabayı çalıştırdı 👏 Araba çalışır vaziyette iken 20 saniye geçmeden hemen powerbank’i aküden ayırdım. Anladığım kadarı ile ayırmazsak göstere “RC “ ibaresi beliriyor ve bu da bu sefer akünün powerbank’i şarj etmeye başladığını gösteriyor. Bu yüzden araç çalıştıktan sonra hemen powerbank’i arabadan sökmek lazım. Ona buna rica minnet edip takviye tantasını çekmemek için birebir 👍🏻 Read more

Purchased this about 5 months ago and have just had the 'opportunity' to actually test it's jump starting capability. Obviously very compact and clearly a great high capacity USB power bank. BUT, the only reason anyone buys this is for the jump start function. IT WORKS! A neighbor had a TOTALLY depleted battery on a 3.5 liter Subaru. Although well below the 7.5L advertised capacity, any dead battery makes for a good test. INSTANT START after connecting. Easy, flawless, as advertised. Read more

Although this device works well, unfortunately, it would loose 50% of the charge for every use... This means u can use it only 2 times per every 100% recharge.... Read more

Easily turns on the car, very rigid and good quality Read more

After two months of using this product, I feel confident in sharing my experience. Initially hesitant, I waited to provide a review until I had thoroughly tested it. Twice in the past two months, my car's battery discharged unexpectedly. On both occasions, I turned to this product as a last resort. With a bit of skepticism, I connected the wires and plugged it into my battery. After a mere 4 to 5 seconds, I switched on the ignition, and to my surprise, my car roared to life. The first incident was in March, and just recently in April, I faced the same issue. Yet again, this product came to the rescue. With just 5 to 10 seconds of charging, my car started without a hitch. Not only did it save me from the inconvenience of calling for roadside assistance, but it also saved me money by avoiding costly garage visits. I highly recommend giving this product a try. It's proven its worth in my experience, and I believe it could do the same for you. Read more
