70mai Jump Starter, 600A Peak Current, 11100mAH, for Petrol Engines Upto 4.0L and Diesel Engines Upto 2.0L

Hi all, I did buy this product very recently since my battery was draining and had no clue about the reason therein. Also was looking for some device to keep it handy for any such issue where in battery dies and a jumpstart would be required.The device looks amazing and the packaging is superlative indeed.The product arrived within couple of days and my Car’s battery was drained yet again. Went through the manual which has explained as to how to use the product. (Even if you are a novice even then you can use the device with little care and handling. )Applied Positive and Negative properly to the corresponding nodes of my car battery and tried cranking the engine and VOILA!!!! It started!!!Took my vehicle immediately to the nearby service station to get the electric issue checked and they confirmed that the battery is the issue and it needs replacement.Well since the battery was concord already I was not able to crank it again. But well had the jumpstart with me and used it right in front of the mechanic and engine came to life. Even he was shocked to know about the utility the device provided. (He even took the photo of the device so that he can order and keep it and perhaps use it when they get any jumpstart calls. Ideally in those situations they have to carry heavy battery and jumpstart cable. But device is like one can carry in the pocket and switch on the engine - it’s that simple!!!Now the device will rest in car along with other utilities like Tyre inflator, Puncture kit etc. Best part is that it can be used using your cars USB port too. So may be once in a month just put it to charge and you are good to go.. and YES... it’s an massive 11k power bank so you can charge your phones too using the USB socket and it has a small Led bulb too in case you need it.5/5! Just keep such useful device in your car... Tks for reading out.

Great features:It is a must to have product in you are on the road.Single Charge lasts for over 3 months if you are using it for only jump starts.It can be used as a battery backup - power bank as well, easy to carry. It comes with a carry bag with 2 sleeves. So, you can keep the battery and the car charging cords in it. Its compact, so can easily fit in the front car compartment as well.Even when the battery charge status is 2 bars - it jump starts the car instantaneously.During the lock downs, my car battery had completely drained out, still it was able to jump start the car seemlessly.

One star removed as they are selling Chinese product in the name of India. Otherwise, it's a worth giving five star.Now review : I've NISSAN TERRANO. When tried to start my vehicle before two months back, it's battery was fully dead. So left as it is. Got this product recently and was little suspicious whether it'll work as it's more than 2 months when car's battery was dead. But when used, to my surprise, it Ignited fully dead battery within a second.Thumps up.

My purchase of the year!!!Due a low running my beloved car usually parked for months and months and battery drainage is very normal in this scenario. Many times no help available at my location so I ordered this bit expensive battery pack jump starter and from the day one it is doing the job perfectly. I even didn’t charge it once but I Charged my car more than 10 times. Trust me it’s a Very best and reliable device and also very easy to use.

Great one..the battery drains faster in three or four attempts

I purchased the 70mai Jump Starter (600A, 11100mAh) in June 2023 and used it only to jump-start my bike occasionally. I always charged it responsibly and never overcharged. Still, within less than a year, the battery started swelling, making the device unsafe to use.I reached out to 70mai customer support explaining the issue in detail, hoping for at least a repair or replacement option—even if paid—but received no response whatsoever. Extremely disappointed by the lack of support, especially from a brand I trusted.If you're considering buying this product, please think twice. It may work initially, but battery safety is critical, and with no after-sales service, you're on your own if things go wrong.

Amazing product. U was able to help a tempo traveller guy when his aantreey was down. This thing is quite powerful.

Portable jump starters really give you peace of mind about car batteries. I jump-started my car 5 times with this thing while on a trip, because my car battery gave out. I didn't have to worry about getting stuck in the middle of nowhere. Really good purchase.
