Can 5V work on 6V?
No. To regulate 6V down to 5V you need a switching regulator or Buck converter as it is known. You do not have enough excess voltage for a linear regulator unless you use a low dropout type.
Can I use a 6V adapter for 12v?
– Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.
Which wire is positive on an AC adapter?
The positive wire should be the one with the white stripe, and the negative wire should be black.
Can I use 12V 1A for 6V 1A?
No you can’t. But 6V power source on 3V items is not acceptable. It’s 2x higher. And so 12V on 6V not to say 3V or even 1,5V.
Can USB handle 6V?
Short answer : no. 6V is too low to be applied on the Vin pin (need at least 7V for a reliable operation) and is too high to be applied on the 5V pin (it’s too close to the safe limit and you might destroy the MCU). You may not use the 6V on the usb bus. It will damage the ATmega2560 chip, and maybe more.
Will too little amperage hurt a device?
The problem, of course, is the reverse: if your device needs 1.0 amps, but your charger is rated at only 0.5 amps, then any of several problems could result: Charging may not work at all. The device may charge extremely slowly. The power supply may overheat.
Can I power a Raspberry Pi with 6V?
A 6V battery is NOT suitable for a PI, it needs at least a 5V regulator (preferably a switching one, preferably one that can work with the full range of voltage from your battery, depending on its charge).
Is a 1 amp charger good?
Many cheap chargers nowadays still max out at 1 amp. Yes it would work, but as others pointed out, it’ll charge much slower, if at all. It also may put more stress on the charger itself by being run right at maximum output all the time, and cause it to fail quicker.
