Best Marine, Industrial, Truck, and Car Jump Starters
Marine, Industrial, Truck, and Car Jump Starters category includes information and reviews of portable, multifunction jump starters that may help one to start the engine when the main battery is being discharged below the level required for cranking the engine.
Car Jump Starter Batteries
Modern portable car jump starters are being powered by lightweight, yet powerful lithium batteries, being able to provide a huge amount of energy in a relatively short period of time. As such, car jump starters come with numerous safety features, making their use as safe as possible.
Nonetheless, it is highly recommended to read the manual/Owner's Guide of your new jump starter when it arrives and to keep it with the unit, just in case - better safe than sorry.
Typically, portable car jump starters feature lithium batteries with a nominal voltage of 3.6-3.7 volts and a capacity of, for example, 18000 mAh (18 Ah) - such battery is able to store 66.6 Wh of energy.
While capacity is an important variable, it is also very important to know the voltage of such battery pack and the amount of stored energy - for example, lithium battery pack consisting of four 3.7V 10Ah cells connected in series features nominal voltage of 14.8V, capacity of 10Ah and is able to store ~148 Wh of energy, which is much more than 66.6 Wh of energy from the previous example.
Car Jump Starter Current
Another important features are the initial and the maximum (peak) current that the jump starter is able to provide. Usually, peak current goes from 500-600 Amps for smaller models to 3000+ Amps for industrial and commercial models.
On average, the initial current is roughly half of the peak current that the jump starter is able to provide.
When cranking the engine, it is important not to crank the engine for too long - car jump starters are compact units that may overheat quickly. If the engine doesn't start after 2-4 seconds (jump starter model dependent), stop with the cranking, let the jump starter cool down for at least 30-60 seconds (or more), and then try again.
If after several attempts the engine doesn't start, let the jump starter cool down for several minutes and then try again.
Note: each jump starter is able to crank the engine several times on a single battery charge, but this number of attempts depends on the engine size, temperature, battery condition, etc, and varies from model to model.
Multifunction jump starters often can be used as LED flashlights, power banks, and similar, which can be great in many situations.
As LED flashlights, most models come with High, Low and Strobe white LED light modes, combined with a red emergency light.
As power bank, most car jump starters feature USB charging ports for recharging of the smartphones and tablets, while certain models come even with variable 12V/16V/19V ports and various port adapters for charging of other devices, laptops included.
However, when such a multifunction jump starter is used for other purposes, one risks discharging its battery below the level required for safe engine starting.
For short - don't use your jump starter for other purposes, unless your engine is already running. And after the use, recharge it completely. Again - better safe than sorry...
