Compare. Ifyou have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it. Those pedals will work perfectly fine with a 12V adapter. 2Answers. Sorted by: 3. TL; DR: Your / Leo Notenboom's assumption ( "Voltage is pushed, Amperage is pulled") is correct, but there are more things to take into consideration than just Volts and Amperes: polarity and connector-compatibility. The more current your PSU can handle, the better (if we are leaving efficiency aside). Heres a photo of the official Black and Decker replacement charger, you can see it outputs 15.3V . Black and Decker EPC12 PSU. The 12V battery of the EPC12 actually needs from 14V to 16V to adequately charge. Anything less, like 12V, and the battery won't charge. Here's the replacement PSU for the EPC12 on the myVolts website - we find Thisis because even I had the same problem. So all u need is a high voltage (12v) transistor and the other parts : arduino, 12v adapter and relay. Now connect the vcc of relay to 12v adapter. Now connect the one end of the transister (refer to data sheet) to 12 adapter connect the middle pin of transistor to one of the pwm pin of arduino . Inthe mild-hybrid system, a 48V battery is added alongside the traditional 12V battery. "There is either an 800- or 400-volt battery in the vehicle. Vicor takes either the 800 or 400 volts from the battery and converts the power to 48 volts for powering loads such as the electric turbo, headed windshield and cooling pumps. Theknob can be adjusted more evenly, and it can reach 13V ~ 14V by rotating 50%. 2. Increase the off gear to turn off the power without pulling the plug. 3.Add a polarity converter cable, which make it compatible with more devices，doubles its range of application. Can be applied to almost all commonly used electronic devices.

Butconsider this: an automotive bulb may be rated at 12V but it is designed to work across the range of voltages present on the car electrical system. With the engine running fast the alternator will output at least 14V. With the engine stopped the battery provides a voltage between 11V and 13V depending on its state of charge.

You just input the total wattage of the device you want to run on a 12V wire, and you will get the min. wire amps (accounted for the 80% NEC rule as well).

But I am worried about the Amperage since a heavy current will fast charge and damage the battery. YTuYjmw.
