Lithium Jump Starter

Having a lithium jump starter in your glove box is a convenient way to save time and frustration when your car has a dead battery. Unlike a lead acid jump starter, lithium jump starters are slim and compact yet powerful.

Avoid the confusing “Cranking Amps” rating of some jump starters and look for a defined Cranking Amp Rating, such as 1min20sec.


A lithium jump starter is like a Swiss Army pocketknife and first aid kit for your car. It is portable and compact and provides everything you need to get your car back on the road quickly, without having to rely on others or expensive roadside assistance services.

Lithium-ion battery technology allows for a much smaller and lighter device than lead-acid batteries. They also have a longer cycle life, so they can be recharged and discharged many times over without losing their capacity. The power of a lithium battery jump starter is measured in Amps, which is how powerfully it can crank the engine of your vehicle to start it. Generally, the higher the Amps, the more powerful your device will be.

Larger lithium jump starters provide more Amps of power than small ones, since they use many individual cells in parallel to increase current capability. They also have advanced safety features to protect against things like short circuits, reverse polarity, overcharging and over-discharging.

When using a portable lithium jump starter, be sure to follow the manufacturer’s instructions for charging and discharging. It is important to keep the device away from flammable materials and avoid exposing it to extreme temperatures. You should also avoid parking the device in direct sunlight, as this can significantly elevate the internal temperature of the battery.


The technology behind lithium jump starters has expanded a lot in just the last ten years. They are far more versatile than lead acid jump starters, which have a longer history and are characterized by their bulkiness and weight.

While both types of jump starters move ions between electrodes to produce electricity, the chemistry is very different. Lead acid batteries contain six cells that each store just over two volts, while lithium jump starters have just one or several larger battery cells. These cells are filled with a dissolved lithium salt solution instead of sulfuric acid. Lithium jump starters are also able to hold much more power in their smaller size.

A good lithium jump starter has a wide range of safety features. lithium jump starter You want to make sure you get one that has reverse polarity protection, spark-proof connections and an overcharge warning, which will prevent the battery from getting too hot.

You also want to read the manufacturer’s specifications carefully to find out how many jump starts a lithium jump starter can deliver before needing a recharge. You can often find this information on the manufacturer’s website or in their user manual. If you plan to use your lithium jump starter a lot, you may want to look for one with a higher energy capacity (measured in watt-hours). This indicates how many jump starts the device can deliver before needing a recharge.


A lithium jump starter packs a powerful punch in a compact form factor that makes it ideal for portability. They work essentially the same way as lead acid jump starters, with the added benefit of USB outputs to charge mobile devices and lights for illumination when needed.

Unlike lead acid jump starters, these portable battery chargers feature mistake-proof connections and reverse polarity protection to prevent sparking or damage. They also meter power so that you don’t overcharge your car’s battery, leading to sulfation or a surface charge.

When you need to use a lithium jump starter, simply connect the red clamp to the positive terminal of your vehicle’s battery (usually marked with a plus sign (+) or the letters “POS”) and the black clamp to the negative terminal. Some models also include features like pre-boost technology to safely add a charge to lithium battery wall mount deeply discharged batteries and a pre-heating mode to warm up cold battery cells for better performance.

Whether you’re using your lithium jump starter to start a dead vehicle or to power up and illuminate your workspace, this portable tool will come in handy more than you might think. Having one in the glove box or trunk can eliminate the need to ask a friend, co-worker or taxi driver for help, and it could even save your life if you find yourself stranded.


Thanks to major technological improvements in batteries, you no longer need to flag down a neighbor, friend or roadside assistance service to jump your car battery. Now, you can take matters into your own hands with a portable lithium jump starter. These little power packs and booster cables fit in your glove box, under the seat or in the trunk of your vehicle. They’re just about the size of a smartphone and weigh under a pound, so they’re easy to store anywhere you might need them.

Lithium jump starters look a bit like the portable power banks that you use to charge your mobile devices, but they have special output cables that connect to your car’s battery. These output cables are conductive and flexible enough to reach any connection points on your vehicle’s battery. They’re also designed to prevent sparking or short circuits and they’re made to withstand extreme temperatures.

The Gooloo GP4000, for example, boasts 4000A peak current and can jumpstart all petrol or diesel engines up to 10.0-litres. It also triples as a power bank to charge your devices, and it has a super bright LED flashlight with three modes and an emergency strobe. It also has 10 safety protections including overheating, over-voltage and internal battery protection. Just be sure to follow the manufacturer’s instructions on charging time and frequency so that you don’t overcharge your jump starter.
