Can I use a 15V power supply on a 12V?
Onus : Assuming the polarity is correct, plugging in a 12V input to a device requiring 15V won’t do any damage, however if you undervolt an amplifier, you may get clipping or other distortion.
Can I use 18V adapter for 12V?
18V would be risky, I would not try to plug a 12V device into an 18V battery. But if you happen to have 18V for whatever reason, you can always use a DC-DC converter. I use car-plug type adapters for all my 12v equipment because they have fuses in them.
Can I use 19V charger for 12V?
NO you cannot charge your 12V AGM battery directly with a 19V Laptop power supply. You need a battery charger. The laptop power supply IS NOT a battery charger, it is a fixed voltage SMPS power supply.
Can I use 500mA instead of 100ma?
You cannot go higher on VOLTS, which will damage your gear. The pedals will draw as much amperage as they need, up to the stated limit. if your pedal needs only 100ma, then that is what it will pull, even if plugged into a 500ma outlet. Higher AMPS = OK, higher volts = BAD.
Will a 12 volt charger charge a 16 volt battery?
6 Answers. Your 12v adapter would only be able to raise the battery voltage to 12v, but to charge a car battery fully you would need to raise the voltage to 13.8v. The 16v adapter would raise the voltage too high and could cause damage.
Will a 14V charger charge a 18V battery?
All DeWalt chargers are designed to only charge that particular battery so you’re 14V battery won’t fit the charger. Plus, charging a 14V on an 18V charger will likely result in an explosion.
Can you charge a 12v battery with a 16v charger?
Can you use a 19V adapter on a 15v device?
No! The adapter will charge the battery very slowly, however the power adapter voltage being 4 volts higher than the battery rated voltage will create a problem that will damage the battery.
Is it safe to change this to 9V DC 1A?
Is it safe to change this to 9V DC 1A? Or perhaps to 9V DC 2A? No, it’s not safe to assume that either of those will work. In fact, even if you did find a “8V 2.6A” power adapter it might still not be safe unless you also know whether the old power adapter was regulated or not.
How to drop from 15V to 12V at 5Amps?
Thanks in advance. To drop from 15v to 12V at 5amps , that is drop 3volts at 5amps requires a 0.6R resistor, rated at LEAST 15Watts. To be sure it didnt get overheated I would use a 25Watt or higher resistor.
How many amps does a 12V cooler draw?
As pointed out, the cooler will most likely accept the 14.5Vmax that occurs when the battery is being charged. BUT. Its a 12V 60Watt cooler, so it will draw 5 amps from a 12V supply. Assuming the cooler absorption heater is resistive, that makes the resistance of the heater approx 2.4R.
Can you replace a DC power supply with another?
Then you would look for another adapter with those same features. Anything else is a risky assumption. However, without additional information, you can almost always replace one power supply with another that has the same voltage output with an equal or greater amperage output.
