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

First Review : Its been 10 days since i got the product. I have a diesel renault duster 1500 cc car with big time battery problems. My battery is not charging even when running, so every time i have to use the jump starter. Got to say it has worked every time i had to use it. 1st Scenario : 100% jump starter charged and fully drained car battery - Didnt connect properly with car battery and so jump starter got drained immediately to 50% when jump starting. But then connected properly in the next attempt and car started in a second. 2nd Scenario : 75% jump starter charged and almost drained car battery - Connected properly and car started in a second. 3rd Scenario : 50% jump starter charged and almost drained car battery - Didnt connect properly with car battery and so jump starter got drained immediately to low level and red blinking when jump starting. But then connected properly in the next attempt and car started immediately even with a totally drained jump starter blinking red(measure for low battery - needs recharging). Positives : Excellent product when used properly and starts the car immediately. Works at all battery levels. Jump starts effectively a totally drained car battery. Will work atleast 10-20 times as per my opinion when totally charged. Possibly even 40 times as mentioned in the product description. Jump starts your car even when showing low battery and blinking red on jump starter. Used multiple times within a 5 minute time frame. Didnt overheat the product but would recommend to disconnect and reconnect for each attempt. As advised give a 2 minutes gap every time when attempting to jump start, even though for me it worked even with a minute time gap. Negatives : Battery gets drained very fast if not connected properly and trying to jump start(25% in each attempt). Even resets your car pedometer and radio settings when trying to jump start if not connected properly.

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.

Very good quality I tried it once with my Toyota Fortuner. It's a very useful and nice products

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.

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.

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.

Brilliant piece of tech. Built well. comes in a handy and sturdy pouch/carry bag. Have jumped my bike a few times with the originally delivered charge and despite it been in my car boot for about 6 months now, its hardly dropped a point. Boosts within a second and so convenient that anyone can use it. Pop open the bonnet and connect the cables, press boost and start the vehicle. That's it.. no more hassles of calling someone to boost your battery.. And it will pay back its value in about 30 boosts.. not to mention its added features like torchlight and usb ports to use as a handy mobile powerbank..

I have a baleno 2018 model 1.2 Delta. I had replaced my original battery in Jan 2019 as it got fully drained in highway and I had no option but to buy a new one. I packed the original battery and kept it in a box since 2019. The second battery gave out last week due to some issues and I had given it for warranty claim. I bought the 70mai jump starter. Suddenly I remembered the old dead battery which was sitting in the balcony since 2019. Fixed the battery on the car but no display came as it was dead. Connected the 70Mai jump starter and pressed the boost button, some charging sound came. Went inside the car and started it. Voila!!! My car started smoothly I was totally stunned. So don't believe those who said that this product doesn't work on dead batteries, it does provided ur connections are proper, jump starter is fully charged, boost button is pressed and you give the ignition within 30 sec of pressing boost button. I tested the same 3 times to confirm. Guys, this handy tool is a life saver in emergency situations. Late i even started my car with this jump starter after removing the battery from the car(with boost ofcourse). So get this for your own good. It's value for money product.
