Can I use 500mA instead of 1000mA?
If the device requests 500ma and the power supply can handle up to 1000ma, it’s fine. The device will only draw what it needs and no more. If the device demands more ma than the power supply can deliver, it will force the power supply to deliver it anyway thus frying the power supply.
What does mA mean on charger?
The abbreviation mAh stands for milliamps per hour and is the unit that indicates how long (per hour) the power bank can deliver a certain amount of current (mA). A standard adapter with a smartphone has an output of 1000 mA. When you charge your smartphone for an hour, your smartphone contains 1000 mAh.
Is 5V the same as 1A?
When charging a 5V/1A phone, the 5V/2A charger and the 5V/1A phone charger have the same current, but the 5V/0.6A charger current is slightly lower and the charger is overloaded. So as long as it is a regular charger, such as the original phone charger, it can be compatible.
What is A milli amp?
Milliampere, or milliamp: 1/1000 of an Ampere. Ampere is the basic unit for measuring electrical current.

Is 1A or 2.4 A faster?
If you plug a 2A device into a 1A charger, you will only get 1A. The device will charge more slowly (1/2 speed roughly) but everything will be fine. see less It is perfectly safe to plug a device that draws 1A into the 2A port and vice versa. Amperes are a measure of current capacity.
What does 1.0 A mean on A charger?
There’s a range of Amp currents for different charging products. 1.0A means that there’s a 1.0 Amp of charging speed. 1.0 is the slowest charging speed and should be avoided with most charging electronics. Standard Amp charging for chargers are 2.0 Amps and 2.1 Amps.
