What experts liked

Other Products We Considered.
- BestReviews
This device comes with a very well designed and sturdy carry case housing all the accessories: mains and 12V car cigarettes socket chargers, jump start charging clamps, and a USB cable. The power pack contains a compass and a bright flashlight which are quite useful if your car breaks down in the dark. There is plenty of power to jumpstart a car with a flat battery and it is lighter than the conventional jumpstarter.
- Best For Driver
In spite of being compact, it still has enough power for even relatively large vehicles. You don’t have to worry about this not being able to get you going again. As well as having two outputs for charging devices, it is pretty simple to charge.
- Battery Focus
Over-charging and wrong-polarity connections is not a problem with this jump starter either. It uses a smart protect-monitored system.
- Mechanic Base
The heavy duty clamps and cables feature overcurrent protection, short circuit protection, overload protection, over-voltage protection, and overcharge protection. An LCD screen is on the side of the device, displaying how much remaining battery life it has left.

What experts didn't like

The input connector broke, and I can no longer charge it. Looking at it, the input connector appears to be weakly attached to the printed circuit board inside the unit, which seems like a design flaw for a product that gets stored in a car. There is also no clear way to open the unit to attempt to repair it.
- BestReviews
Sometimes, the device does not reach the maximum amperage. According to their observations, the real level remained 500 A.
- Best For Driver
Doesn’t hold a charge as long as some other competitors.
- Battery Focus
Some quality issues with faulty units, poorly written instructions, short cables.

An Overview On Battery Jump Starters For Cars

When car batteries die, drivers can find themselves stranded if they don’t have the right tools. Jumper cables can recharge batteries, but only when they are connected to other batteries. There is always the option of calling for roadside assistance, but if you have a compact jump starter, you can easily charge the battery yourself.

The latest battery jump starters are made with compact lithium-ion batteries. They generally cost less than $100, and the smallest ones are about as big as a book and weigh only a pound. These compact jump starters can start up cars in seconds, and they many have other functions as well.

Some of these chargers have built-in LED flashlights, which is invaluable if your vehicle has broken down in the dark. Look for other features, too, like built-in USB ports, other connectors and air compressors. With all these extras, a portable battery charger can be the most important part of your car or home’s emergency kits.

The Battery Jump Starter For Cars Buying Guide

  • Avoid old-school, lead-acid jump-starters, which do not work as well as lithium jump starters. The former can weigh as much as 40 pounds, and they do not last as long.
  • Check the type of battery your vehicle has before buying the jump starter. Most cars and SUVs work on 6- to 12-volt batteries, and you may need an industrial-grade charger for larger trucks.
  • You will also need to know what type of engine you have before picking out a charger. For example, 4-cylinder gasoline engines run on 150 to 250 amps, and 6-cylinder gas engines run on 250 to 350 amps.
  • Check for safety features like reverse polarity and short circuit protection.
