Can the Wrong Charger Ruin Your Phone (Explained)


It’s not a good idea to use the 5V 1A charger to operate a device that is typically charged with a 5V 2A charger because doing so will likely cause the 1A charger to overheat and, in the worst case, catch fire.

A higher amperage charger will probably charge your phone even faster, and it can do so safely.

What Happens if You Use the Wrong Charger

The device may turn on, but the adapter may not be able to keep up, resulting in the voltage dropping (see voltage too low above). The device may turn on, but the adapter may not be able to keep up, resulting in the voltage dropping.

What Happens if You Use a Charger That Is Too Powerful for Your Phone

If your phone attempts to draw much more current than that, it will significantly overload the power supply; at moderate levels of overload, the result is probably only voltage sagging. A power supply (what you’re referring to as the charger) rated for 1A can only provide up to 1A and still operate within specs.

Does It Matter What Phone Charger You Use

Actually, all modern batteries are built with a chip that regulates the input they will allow what they can handle. A higher amperage charger will probably charge your phone even faster, and it can do so safely.

What Happens if You Charge a Battery With the Wrong Voltage

Voltage too high If the device detects an overvoltage, it will likely shut off by itself; if it doesn’t, it may run hotter than usual, which could shorten the device’s lifespan or result in immediate damage.

Can I Use a 1a Charger for a 2a Device

Can Low Voltage Damage Smartphone

If you don’t have better data, make sure the voltage is 5V; too low voltage isn’t harmful unless there is no charging; too high of a voltage is probably harmful (9V).

Can I Use a 90w Charger Instead of 45w

A 30W or a 45W charger will not be able to supply your laptop with the power it requires, risking damage to both the charger and the laptop if you try to use one.

Can I Use a 65w Charger Instead of 45w

The laptop will only draw the current it requires while running, so using a higher watt adapter as long as it has the same voltage and connector type will allow you to charge the battery a little bit more quickly.

Can I Use 90w Charger Instead of 120w

Yes, since you won’t always be using 120 watts.

Can I Use a Lower Wattage Charger for My Phone

You’ll still be constrained by the lower capacity charger you’re using, and these low spec chargers may not even work with the much larger batteries of tablets, or they may only be able to trickle charge, if you try to charge a high capacity, fast charging phone battery with a 5W or 10W charger.

Can I Use a 90w Charger Instead of 65w

Your laptop’s battery will actually charge faster if you use a 90 watt ac adapter, also known as a power charger.
