If your AC adapter has higher current rating it won't destroy your device. You can certainly exceed the device voltage which is why his AC adapter should be 5V rated. USB is 500mA max but an unenumerated device can only draw 100mA.
Can you turn a USB port into an outlet?
The easy, no-hassle way: Plug-in adapters This plug-in adapter gives any outlet USB ports. Second, it provides 2.4 amps of power across both USB ports—which means it'll charge two phones at once, or one larger tablet, but it won't be able to charge a phone and a tablet at the same time.Nov 2, 2018
Is a USB port AC or DC power?
Standard USB devices have a 5 V dc voltage and a current up to . 5 A or 500 mA for charging only. This is what allows them to play nice with the USB ports on your computer. Most USB wall adapters will be 5 V adapters and have a current rating well over .
What is AC to USB?
NurPhoto/Getty Images. A USB-C cable is a recent type of USB connector that's easier to use and more powerful than older USB types. USB-C cables can be used to quickly charge many popular devices, including the MacBook Pro and Nintendo Switch, and transfer data faster than any other USB type.
What is a USB AC Adaptor?

What uses an AC adapter?
Alternating current (AC) adapters are used to power or charge many common electronic devices, such as mobile phones, laptop computers, or external hard drives. An AC adapter changes AC power from an electrical outlet into the type of power or voltage that an electronic device needs to work.
What is an AC adapter on a laptop?
The AC adapter, commonly called a laptop charger, is used to provide sufficient power to operate the laptop for extended periods and to recharge the laptop battery.
Are power Adaptors AC or DC?
A power supply for electronic devices. Also called an "AC adapter" or "charger," power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop.
Are power adapters DC?
Also called an "AC adapter" or "charger," power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop. The additional DC voltages are created by internal circuits.
