Will 12V work on 19V?

Almost all devices have a range of supply voltages over which they can work without problems, and this range (a.k.a. tolerance) can be as low as 5–10\%, and as high as over 100\% (more than twice the specified voltage). 19V in general is too high for a 12V device. I wouldn’t recommend going any higher than 14–15V.

Can I charge my laptop with 12V charger?

Absolutely, but avoid the inverter and get a 12V charger. The inverter will work of course, but you go from 12VDC to 110VAC or 230VAC back to something like 20VDC (depending on your laptop battery). It’s much more efficient, much less bulky and much cheaper to simply use a step-up DC-DC converter.

Can I plug 12V into 5V?

The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc. Mostly it will get damaged.

Can I use a lower voltage charger for my laptop?

Can I Use Lower Voltage Charger For My Laptop? You cannot use a lower voltage charger for your laptop. The lower voltage charger can charge the battery excruciatingly slow. It might not support the working of the laptop either.

Can I use 19V charger for 15V laptop?

You can not however use a 15V charger on a laptop that requires 19V or vice versa. The output tip needs to match. However, to avoid any damage to your laptop it’s usually a good idea to check the polarity against that of the laptop or your original charger.

Can a 12V power supply be used in a 19V device?

There are examples for different outcomes. If that “12V” device was designed to be used in cars/boats, from the nominally 12V supply that’s around 14V when the engine is running, and might carry transients up to 200V, then it must be able to tolerate 19V. At least for a short time. Other devices are less tolerant.

Is 1919v too high for a 12V power supply?

19V in general is too high for a 12V device. I wouldn’t recommend going any higher than 14–15V. Even if your device works for some time, it will likely get damaged after some time (it could be seconds, minutes, hours, days…). Probably but maybe not . Your question is so vague it would be impossible to answer with accuracy .

What type of power do I need to charge my device?

The input line voltage (wall or “mains” power) must be supported but is unrelated to compatibility with the device being charged or powered. The voltage provided by your charger must match that expected by the device being charged.

What voltage is too high for a 12V to work?

Almost all devices have a range of supply voltages over which they can work without problems, and this range (a.k.a. tolerance) can be as low as 5–10\%, and as high as over 100\% (more than twice the specified voltage). 19V in general is too high for a 12V device.
