Voltage too high – If the adapterhas a higher voltage, but the current is the same, then thedevice will likely shut itself off when it detects anovervoltage. If it doesn't, then it may run hotter thannormal, which can shorten the life of the device or causeimmediate damage..
Herein, can you use a higher voltage power supply?
2 Answers. Higher current (A) is okay because thedevice won't use as much, but higher voltage (V) isgoing to “fry” it. Conversely, lower voltage isunlikely to cause damage since the device simply won't have enoughpower, but lower current can cause trouble becausethe power supply cannot provide enough.
Also, will using a different charger ruin? “The fluctuation of voltage can damage thecharger port, and even damage your battery.” Ina pinch, an off-brand cord probably won't do as much damageas a knockoff of the piece that plugs in to the wall or car might.But your best bet is to stick with manufacturer-certified products,says Nichols.
Additionally, can I use a higher voltage charger for my laptop?
Using a charger with the wrongvoltage rating can potentially damage yourlaptop. This is typically caused by too high voltage.But using a charger with too high current won'tdamage your laptop. As the difference in voltage inthis case is small, it should be OK.
What happens if we charge phone with higher amperage charger?
For some older devices, the higher speccedcharger just won't work at all, while newer devices willjust charge faster. Ultimately, it's really theamperage that determines how fast a charger willsupply power to your device. If you have a good, highamperage charger, you can cut down on your overallcharging time.
