Can a powerbank jump start a car?You have to let it sit for a bit. This is only going to work if you battery isn't completely dead. Thanks for mentioning although may not be able to jump start a car, these powerbanks may still be able to recharge a flat battery as long as they have higher voltage. Maybe.
Can a car battery run on a USB outlet?No, you can't. A car battery needs a lot of amps at ~12v, and most USB outlets are rated between .5A and 2A at 5v. Car batteries run in the hundreds of amps at 12v. Water hoses often make a good analogy for electricity. Think of amps as the width of the hose, and volts as the speed that the water is flowing at.
What would happen if a car battery plugged into a power bank?It would be a slow process; the thin wiring inside the power banks would never flow enough current to turn the engine (the cables from car battery to starter are as thick as your finger) but it would slowly charge the main battery. How much energy are we talking?.
How do you jump start a car?To jump start the car, you need something with 12-14v and able to crank out 100+ amps. You can charge your battery with anything with a higher voltage. There is a video of someone charging his battery with a bunch of AA batteries in series. You have to let it sit for a bit. This is only going to work if you battery isn't completely dead.
How many amps do you need for a car battery charger?Not enough amps. Depending on the vehicle it could require as much as 300 cold cranking amps. You can't even provide .5% of that with three cel phone battery portable battery chargers. @DucatiKiller Thanks so I should pay attention to the output current if mine ones are > 300amp?.
Can a JSU start a car?Attempts to start the vehicle from a JSU that can supply say 10A when cranking currents are 100s of Amps will be completely unsuccessful. IF the vehicle starts in 2 seconds and IF the vehicle battery can return at least 2/3 of the energy input at an adequate voltage. THEN the vehicle will start. Which is why my original answer was "maybe&quo
