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 (current = voltage / resistance) Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device …

Switch between battery and USB power

The small drop comes from the Operation voltage of one of the ICs, it needs to be 3.5V (min) and the larger voltage drop eats into the battery life. (i.e. 4 battery, 0.9 each, 3.6V, 100mV drop, I can squeeze the batteries). If there is a 0.7V drop, I can not use the full battery power.

Design 5V DC Power Supply (Step By Step Guide 2024)

Please do not specify the above power supply we designed it to just be a 250mA supply. It can be your 5V DC power supply in general with up to 250mA current capability. This means you can use it for the current range of 0 – 250mA. Far from this range, the power supply will degrade its performance as it is only designed for this range.
