How to choose the right Charger?To choose the right charger for the right device increases the rate of charging, increases the lifespan of the device and decreases the risk of burn. There is always a risk of burn, but it can be minimized by many methods. Ohm's law V = R I where V voltage, R resistance, and I current.
Is it safe to charge a device with more current capacity?Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Ohm's law tells us the relation between current, voltage, and resistance: I= V/ R.
What voltage does a USB charge a smartphone use?For most USB chargeable smartphones the battery voltage is irrelevant. The USB charging circuit is often set to 5 V 0.5 A USB1 (5V, 0.5A)5V 2A? USB2 (5V, 0.5A)5V 2A? USB3 (0.9A)5V 2A? USB-C5V 2A? Choosing power supply, how to get the voltage and current ratings?.
What is the Apple standard for charging a battery?The Apple standard has been loosely adopted by others, or is accepted by others, and consists of placing specific voltage levels on the D- and D+ lines at a low current. Placing approximately 2.0V on the D- line, and 2.75V on the D+ line will signal 2A (10W) is available for charging. This can be done with simple resistors:.
Can a 1A power supply be overloaded?A power supply (what you're calling the "charger") rated for 1A can only provide up to 1A and still operate within spec. If your phone tries to pull much more than that it will excessively load the power supply. At moderate levels of overload the result is likely only the voltage "sagging".
What spec should you consider when buying a power station?Whatever the reason you are purchasing a power station, the most important spec to pay attention to is watt hours, which is a measurement of how much energy the power station can hold. While a particular power station might claim to hold 1,000 watt hours, the actual amount of usable power you can get out of it is a different sto
