BESTEK 400A Review

The BESTEK 400A is more than just a jump starter, it actually acts as a portable power pack. This means that if the power goes out, you can easily recharge all of your mobile devices, including your smart phone, tablet, or laptop.

Let’s take a closer look at what the 400A has to offer.

Jumpstart Your Vehicle

The 400A can easily jumpstart a 2.5L diesel or a 3L gas vehicle. With a 400A peak current and an 1100mAh battery, this device can jumpstart a vehicle 16 times before needing to be recharged. Despite its small size, this charger is powerful enough to jumpstart an SUV, like the Honda Pilot.

Unlike other jump starters, the jumping cables are not actually attached to the device. Rather, they plug into the 400A, and then hook up to your vehicle.

These advanced, smart jumper cables are provided for added protection against surges, reverse polarity, and short-circuits. Two LED indicator lights illuminate when it’s safe to start your vehicle, or if something is wrong. Not only does this protect the jump starter itself, but your car battery as well.

Battery Charger

With dual USB ports, you can easily charge your iPhone or Android smartphone, iPad, tablet, laptop, or any other device.

So, if you’re stranded in the middle of nowhere and your car battery dies, you can ensure that your cell phone is still working in case of emergency. Or, if the power goes out in your home, you can still use your phone.

Compact and Lightweight

What really makes this jumpstarter unique is its compact size and light weight. This device is small enough to fit in your back pocket, glovebox, backpack, or purse. This means that you can easily take it with you anywhere. Whether you’re traveling with friends, going on a long road trip, or just headed out for a night on the town, you can bring the 400A with you just in case.

Bright LED Flashlight

In addition to its charging ports and jumpstarting capabilities, the 400A also includes LED lights that monitor the battery level and serve as a flashlight for you. So, if you’re stranded in the dark, this jump starter will ensure that you can see under the hood for safe jumpstarting.

  • Lightweight and compact

  • Battery needs to be charged often

In order to extend the life of the battery, BESTEK recommends charging at least once every three months. If you don’t use this jumpstart often, you may forget to recharge the battery and may face issues during future uses. That said, most people have no problems keeping up with the three-month recharge requirement.

After putting this model to test, it not only jumpstarted our vehicle, but also charged our tablet and smart phone surprisingly quickly. It’s so lightweight and compact that it’s hard to believe this device has enough power to jumpstart a vehicle – but it does. It fits nicely into any size glovebox, and can easily be carried in your pocket if necessary. We highly recommend the BESTEK 400As for anyone looking for a reliable, compact jump starter for their vehicle.
