6-24V to 5V 3A USB step-down module (1A)
Product key benefits:
-
Voltage range for input specified by the manufacturer: DC 6V-20V (minimum input voltage determined by testing is 5V)
-
Output current up to 3A
-
This is a buck (step-down) module that can only lower the voltage to the target value.
-
The module has a red LED indicator that shows when power is connected to the module.
-
The module can be used in car chargers, as a charger for a connected low-power solar panel or Li-Ion batteries.
-
The module does not support fast charging protocols, which may be convenient for those who consciously prefer a slow charging process to extend the life of the battery of the device being charged.
-
The module is very compact and inexpensive (about $1 on AliExpress).

XY-3606T step-down module with Alu shell (4A)
Product key benefits:
-
Voltage range for input specified by the manufacturer: DC 9V-36V (testing determined a minimum voltage of 8.2V)
-
This is a buck (step-down) module that can only lower the voltage to the target.
-
The module has a red LED indicator that indicates that power is connected to the module.
-
There are two power options: 5.5x2.1mm jack or D+/D- terminals.
-
