hello, if you find your RD power supply cannot output current when take a load, you can check it in this way, do you connect the battery and reverse the connection before, and you can set 5V 1A and short the output, turn on the output to let me check the real output voltage and current
there are 2 days left for the April promotion, if there are still some products in your wishlist, you can make the order, the price is already lower than normal, it is a good time to order RD6030-max, RD6024, RK6006 etc.
