    • Great product!
Color: WHITE(4120A)
I've had to use this product a handful of times since I purchased it, and had to come back to write a review! Product works great! It's very easy to use - you can't mess it up! It's well built and holds its charge for a very long time. Highly recommended. No more jumper cables!

    • Good Battery Life. Strong plastic smell
Color: WHITE(4120A)
I have tried the following Jump Starters and since most of the time I will be using it for charging devices my review is for how good the batteries are for charging mobile devices and how well they hold the charge. They are all over 2500A and do a good job with jump starting of my SUV. My recommendation: If you don't need voltmeter and digital display then any of the DBPower jump starters or Yester are good. If you need voltmeter then Mostools and Imazing are the best. Mostools M6 3000A - Looks high quality product with one of the thickest and biggest jump starter cables. - Takes less than 5 hours to charge - Good battery. Can charge over 3 Mobile phones - Plugging in phone automatically starts the jump starter and when done automatically powers off the jump starter. - Very powerful LED light. 2 separate power buttons for charging and LED lights. - Large Display and good case. - Contains Voltmeter to measure the battery level of Cars battery. However once charges the Jump Starter turns off and you cannot see after charge battery level. The manual says that when the output battery voltage is higher than Jump Starters battery voltage it turns off. - All the USB ports are 3A for fast charging which helps with quick charging your mobile devices. - Also the only one in the list which comes with charger. - 24 months warranty. Support is available through Seller messages to NCYJC. - Bad: Their phone no and emails on the user manual yield no response. There is no cigarette lighter adapter. YaberAuto 3000A - Small one and doesn't look high quality - Takes upto 6 hours to charge - Bad for charging. Only one mobile phones charging takes up 80% of the charge from the jump starter battery. - Need to start the jump starter to charge and need to remove the plugged in device to automatically stop it. - Average LED Light. Power and Lights are controlled from the same button with long press for lights. - Small display - Contains volt meter on the charging cable - 2.1 and 2.4 A USB ports only so no fast charging for latest mobile phones - No charger for the jump starter - 24 months warranty however there was no response to my questions/requests from their website. DBPower 2750 & 3000 - Very high quality and compact. The best looking in all I have reviewed. Jump starter cables are still better in Mostools - 5-7 hours to charge the jump starter battery - Good battery. Can charge about 3 Mobile phones (for 3000A over 3 mobile phones) - Need to turn power on to charge mobile device - Average LED lights. One power button for both LED and power. - No display and excellent case. - No Voltmeter - Fast charge available USB Ports. USBC in out and 1 USB fast charge port. One USB port at 2.1A - No charger for jump starter - 12-18 months warranty. Best customer service in this entire list. You can chat online from their website and they follow through to closure. The warranty varies by product so please check warranty. Buture 2500A - Average quality and everything is similar to YaberAuto hence not highlighting all the points. - Bad for charging. Only one mobile phones charging takes up 100% of the charge from the jump starter battery Yesper 4120A - Good quality. Although had plastic smell the most out of all in this list - Takes 8 hours to charge the jump starter - Good battery. Can charge over 3 Mobile phones. Plugging in phone automatically starts the jump starter and when done automatically stops the jump starter - Average LED lights. One power button for both LED and Power - No display and excellent case - No voltmeter - Fast charging available including USBC in/out at 3A - No charger for jump starter. Cigarette Lighter female cable available - 18 months warranty. No response for my queries from Yesper site Imazing IM29 from Costco - Good quality however a bit expensive compared to all the above - Over 5 hours to charge the jump starter - Good battery. Can charge upto 3 mobile phones. Need to start the jump starter to charge the mobile device. - Average LED Lights. One power button for both - Display available and excellent case - Some reviews say that voltmeter exists however the one I purchased didn't have voltmeter on the cable - Fast charge available USB Ports. USBC in out and 1 USB fast charge port. One USB port at 2.1A - No charger for jump starter. Cigarette Lighter female cable available - 24 months warranty. No response from support which is why I returned this product ... show more

    • Will start your car without a battery.
Color: WHITE(4120A)
Nice built in safety feature so you can get shocked. Will jump almost any car or truck if any size. Big diesels may need to look elsewhere. It's built very well uses a USB C charging cable. Takes 1 minutes to use. Very strong jumpbox. Can also be used to charge your phone or laptop or any portable device using its two USB out ports. Has a lot of power. ... show more

    • Powerful
Color: WHITE(4120A)
After seeing this jumper on the Project Farm YouTube channel and saw how well it performed I bought 1 for myself. I had to use it on my wife's car shortly after it arrived. The car started up immediately without having to wait for the dead battery to charge up. I've also used it on several neighbors' cars since. I just bought a 3rd one as a gift for my son and his wife. Better than and easier to use than conventional jumpers. ... show more

    • Start battery of SUV Evoque in one click. Very happy!
Color: WHITE(4120A)
We received this product, Yesper, with 3 bars and we charged it at full of 4 bars . Then we try to start 2021 Evoque which has a dead battery for not using for 3 months. SUV started in one click and we were happy it worked. We let the SUV run for 20 minutes before we drove to our destination. However on our way back home, the SUV won't start again. We brought Yesper in the vehicle so we jump start again with still battery juice of 4 bars. SUV ran again in 1 click. However, our SUV has the auto on/off button and when we got into a stop light, the SUV battery died again. It was dark and cold , In the middle of the road with no hazzard light. We jump start again with remaining 3 bars and Yesper didn't fail us. Now we named our jumpstart "Yes Per to Yes Monster" for its monster capacity and reliability. Two thumbs up. So very highly recommended. ... show more
