🎃 Can You Use A 12V Adapter For A 14V Device

Canyou use a 12V adapter for a 5V device? 5 Answers. Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger. No you cannot use a 12V 1A power adapter on a 12V 1. 5A device. The power adapter must be rated for the same or higher amp (current) rating than the device. If a device has a 12V 1. 5A power supply, it needs to be plugged into a 12V 1. 5A power adapter. Using a lower rating is not recommended because it can cause damage to the device and even Thiscan be accomplished by hooking up the output of the adapter to a simple 5V linear regulator, which will probably have a dropout of 200mA. Can I use a 5V power supply on a 12V? So now you know you can get 12V DC from 5V DC but as you increased the voltage, the output current must reduce to respect conservation principle. Canyou use a 14V adapter for a 12V device? In simple terms, using a 14V adapter will result in higher current through the components, which will shorten their life span or fry them. Most '12v' supplies really measure in around 13.6 or so. I think you are fine. Can I use 13v instead of 12V? Yes, assuming it's a regulated voltage supply Ifyou use a boost converter to get 12V from 5V, then the converter will have to boost the voltage by a factor of 2.4. The current drawn from the 5V supply will go up by that same factor of 2.4. 12V at 0.23A means you will have 0.552A at 5V. That's ignoring the losses in the converter. In reality, you will need even more current from the 5V supply. Ifyou use 24 V instead of 12 V, you will dissipate 5X as much power in the 7809 regulator. Using your quoted current of 120 mA, with a 12 V supply you need to drop (12 − 9) = 3 V ( 12 − 9) = 3 V so the regulator is dissipating 360 mW ( P = IR P = I R ). If you change to 24 V you need to drop (24 − 9) = 15 V ( 24 − 9) = 15 V, and then Thisis the simplest LM317 based variable power supply. We can adjust the output voltage of 1.25V to 15V. The output current level of each voltage is different. For example: If you adjust the voltage of 12V, the current level will be 0.5A. When you set the voltage of 15V, it causes the output current of 0.2A. Youcould even call a 12V bulb "14V" because for most of the time it is working at 14V. What should the voltage be for a 12V LED strip? After this minimum threshold voltage, power draw increases by approximately 1.0 watts per foot every 0.75 volt and 1.5 volt increase for 12V and 24V LED strips, respectively.
