Lead-acid jump starters are much larger without necessarily providing more jump starting current than lithium-ion units like the GREPOW Car Battery Booster Pack. Speaking of size, jump starters are based on two primary battery technologies – lead-acid (like your car) and lithium-ion. Again, this depends on the level of depletion as the jump start battery will need to be at optimum functionality to deliver enough voltage to crank the engine’s motor. While working at optimum capacity, the jump starter battery will deliver nothing short of enough voltage to start the engine. Question 4: How does a jump starter battery provide so much amperage given such a small size?Ī:Compact jump starters are designed to give out a massive jolt of current to jump start a vehicle, as opposed to keeping it running for long as the car’s battery does. Question 3: Can you apply the battery certificate UL, FCC and CE for us?Ī:We can apply different kinds of battery certificates for you on your request. If you live in a region with especially low winter temperatures, then you may want to check out our best lithium-ion jump starters. Lithium batteries are said to be somewhat more resistant to performance loss at lower temperatures. In very cold climates, you would need to double this figure again as the cranking capacity of the batteries inside the jump starter diminishes as temperature decreases. GREPOW lithium battery jump starter packs up to 2,000A, it is easy to start your car in seconds. The lowest temperature you’re likely to need your jump starter in should also be considered. For diesel engines, you can essentially double this figure. Typically though, the absolute minimum for most petrol sedans would be about 300A. Question 2: What peak Amp does a portable car jump starter need to be for a sedan?Ī:Again my in-depth guide on choosing a jump starter goes through this. Some jump starters, especially the larger ones, offer 12V connections so you can charge/power anything that is using the standard 12V plug but also 9V sockets that can charge laptops, etc. Ability to charge your phone/iPad via the integrated USB ports is a standard, some jump starters offer even more than one. Question 1: What car and other automotive accessories can GREPOW car battery jump starter power?Ī:GREPOW car battery jumper boxes are amazing in their versatility. LED lighting (luminous flux: 300 LUMENS, 3 modes: SOS/stroboscopic/constant light)ĥ. Built-in air inflator, support tire pressure detection, preset charging and stopping value, unit switching and other functions Īir pressure sensor accuracy: ☒ PSI, maximum inflation pressure 150 PSI ģ. 1.Emergency start of 12V engine (up to 8-Liter gasoline and 6-Liter diesel 12 V engines)Ģ.
