Can I use a charger with less output amperage than the device needs?
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.
Does amperage matter phone chargers?
It doesn’t matter if the power supply / charger can provide more current then the device requires. Providing less current will prevent charging or slow it down the same as a poorly designed charger can also prevent charging or slow it down.
What if I charge my phone with lower amps?
There is absolutely no way lower amperage in any circumstances can damage any circuitry of any sort. The amperage is simply the amount of energy that is being sent into the phone. Less energy = Slower charge time.
Can I charge 1A device with 2A charger?
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.
Can I use a charger with lower amperage?
The amperage rating of a charger or power supply is the maximum it can supply. A device being charged will only take as much amperage as it requires. If your device needs 0.5 amps to charge, and your charger is rated at 1.0 amps, only 0.5 amps will be used. The device being charged may be damaged.
How many amps does it take to charge a phone?
If your device needs 0.5 amps to charge, and your charger is rated at 1.0 amps, only 0.5 amps will be used. The problem, of course, is the reverse: if your device needs 1.0 amps, but your charger is rated at only 0.5 amps, then any of several problems could result: Charging may not work at all.
How much amperage does my Charger need to provide?
The amperage provided by your charger must match or exceed what the device being charged requires. The amperage rating is the maximum amount of power it can supply. A device being charged will only take as much amperage as it requires. If your device needs 0.5 amps to charge, and your charger is rated at 1.0 amps, only 0.5 amps will be used.
How do I choose the right charger for my phone?
Wired explains that picking the right charger with the right amperage (a measure of current) can mean the difference between getting your phone charged while you work versus waiting all day before you can unplug it. This isn’t as simple as just “charge your device with the charger it shipped with.”
What type of power do I need to charge my device?
The input line voltage (wall or “mains” power) must be supported but is unrelated to compatibility with the device being charged or powered. The voltage provided by your charger must match that expected by the device being charged.
