Can I charge my phone with lower amperage?

We recommend higher amperage to ensure cooler power supply and optimal charge time. If you get a charger with amperage less than your original power supply, you risk overheating your charger, burning it and in many case your device will stop functioning and/or charging.

Can I charge my phone with lower voltage?

It is technically quite feasible to charge a battery of a given voltage from a supply at a lower voltage, but some kind of voltage converter, typically one operating in a so-called “switching mode”, is required.

What is difference between 5V 1A and 5V 2A?

Smartphone chargers do affect your user experience. While we know that 5V 2A chargers can charge a smartphone faster than a 5V 1A charger. By simple maths, 5V 2A means 10W – that means double the speed of a 5V 1A charger, right?

Is it safe to charge a battery at lower amps?

If the charging is happening at 2 amps or less then it is fine. If it is charging at more than 2 amps and less than 4 amps then that may be OK but it could shorten the total lifespan of the battery.

Can I charge my phone with a charger that outputs different amperes than my normal charger?

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.

Can I use a charger with lower voltage than the original?

Voltage too low – If the voltage on an adapter is lower than the device, but the current is the same, then the device may work, albeit erratically. Usually, an under-voltage condition won’t cause damage or shorten the life of your device.

Is it safe to use 1A charger for 2A device?

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. The current draw (Amperes) is controlled by the device you plug in. So if you plug a 1A device into a 2A charger, it will still only draw 1A.
