Amazing Must Have! Amazing Must Have!
Size: 8000A
I recently purchased the Auxito Battery Jump Starter, and it has quickly become an essential tool in my vehicle emergency kit. This compact yet powerful device delivers reliable performance, making it a must-have for anyone who wants peace of mind on the road. One of the standout features is its high-capacity battery, which provides enough power to jump-start a dead battery multiple times on a single charge. I tested it on my Pilot and my husband’s Tundra and it worked flawlessly both times. Beyond jump-starting, the Auxito also doubles as a portable power bank with USB ports, allowing me to charge my phone and other devices on the go, which you need as a busy mom for sure! The LED flashlight with multiple modes (including emergency strobe) is a great bonus for any nighttime situations you may encounter. The device itself is lightweight and compact, making it easy to store in my glove compartment or trunk. Plus, the included carrying case keeps everything organized. Overall, the Auxito Battery Jump Starter is a reliable, versatile, and user-friendly tool that every driver should have. Whether you’re dealing with a dead battery or need an emergency power source, this device is worth the investment. Highly recommended!

Huge Improvement Over Old Model!
Size: 8000A
Very nice improvement over the previous model. This model adds a much more sturdy feel, soft touch plastics, longer cables, 3 methods of charging external devices, a display, a force start function, as well as a handle on the carry case. It's perfect timing that I got this, because my girlfriends car battery died not even 3 days after I got it, so I was able to put it to the test. It performed flawlessly and started the car up in less than 30 seconds time. There are only 2 suggestions I have for the next model. 1. The buttons are a bit too easy to press. I feel that a recessed button, or rubber molding over the buttons 2. A dual-molded rubber/plastic body would be very nice to protect it from accidentally drops and scratches.

Great Jump Box
Size: 8000A
These are very durable and quality jump boxes. We've used them to start our 26' box trucks several times so it definitely has the power. Amazing quality for the price. It is light weight and easy to transport and easy to use.

Puts out lots of amperage Puts out lots of amperage

Having the car ready to run before you jump start it. Works really well when it's ready to run. Really enjoy the quality and power this jump pack has. Glad I could test it out. The only thing I can critizise on this jumper pack is going to be the fact that the SOS feature blinks OS instead of SOS

I give up! 6 car battery jump starters from 3 different manufacturers, each NOT recommended!
Size: 8000A
This was the 3rd (and latest) type of car battery pack jumper purchased from Amazon; note the other two make & model’s are listed in this review so you can avoid them as well starting back in 2022. I am officially giving up with respect purchasing any additional battery jumpers from Amazon, I was really hoping that the third time would be the ticket, but alas, this one is also absolute garbage for any size car engine. Charged to a full 100%, they are simply not reliable. The AUXITO 8000A, 20000 mAh battery pack was purchased September 2, 2025 for $89.98, quantity purchased (2). No option for negative stars. The second battery jumper was a UIBI S600 5000A, 26800mAh car battery jumper for up to 10L gasoline or 10L diesel; also would not jump any size engine at 100% charge. Purchased October 22, 2025 for $25.99, quantity purchased (1). This was for a 4-cylinder Honda Civic, so even though it cost less due to a good discount code (obviously I know why now), I definitely got what I paid for!) despite having the specifications that clearly should be more than enough to start a 4-cylinder engine. No option for negative stars. The very first battery packs purchased were the Fanttik T8 2000A, 20000mAh battery pack for up to 8.5L gasoline or 6.0L diesel engines. Initially worked very good, starting my 8.1L V-8 truck engine with no difficulties, they all degraded very quickly over time despite proper care and maintenance, none would jump any size engine, even at 100% charge.. Purchased May 27, 2022 for $84.97, quantity purchased (3). No option for negative stars So, all in, not included taxes, I am in the hole for $460.86 and STILL do not have a reliable battery pack jumper for any of our vehicles, to include my mother, wife, and daughter. I do however have good heavy duty jumper cables in their respective emergency kit as a backup, although not ideal, especially given the substantial investment made. I will say that each model will charge an iPhone relatively well, so it’s not all negative!.
