🔌 DZS Elec Mini DC 5-36V USB Buck Converter Regulator Power Supply Module - Step Down Voltage Module for 36V 24V 12V to 5V 3A USB Charging Review

Works from day one BUT only draws 115mA from the 24v supply and even less, 40mA from the 12v supply. This means that the output power (assuming 100% efficiency) is only 0.72 amps/0.1 amps versus the advertised 3 amps. Far away, I feel like it was advertised incorrectly and I wouldn't buy it.

It was advertised as outputting 5 volts and 3 amps but I seem to only be getting 2 amps, not enough to charge my devices which require 3 amps. Still works great. for all 2 amp electronics with USB for charging. It also appears to be missing components compared to the image on Revain.

For some reason this thing is draining my battery even with nothing plugged into the USB. Didn't expect that. I have to pull out the 9V, I have a cable when I'm not using it, otherwise it's completely discharged the next day. Tested with two fresh 9Vs and nothing connected to the USB port.

I received the item only to find that the items were hand soldered and not manufactured properly. The USB connector was not properly soldered (mounting tabs) and there was flux everywhere. This is the worst quality product I have ever seen. It returns immediately. Not recommended.

When using a 24V desktop power supply (calibrated) the board will output a maximum of 5.1V at 2A before being clipped. I also recorded temperatures at 2A load for about an hour. It was *really* hot: Max: 85.96 Min: 64.02 Ambient: 26.55 Delta: 53.79 C – even without the case! I'm sorry people; Fail. Don't buy this one.

I bought this to use in a ham radio case and needed 5 volts to power my raspberry pi. It works great, easy to use, enough power for Pi3. The only problem is that there are no mounting holes. In the end I screwed the plastic part to the chassis and glued it to the plastic with the E6000. If there were a few holes in the rack it would be MUCH better.

I haven't had a chance to use this board in my project yet, but I immediately noticed some interesting things worth sharing. Although it can be seen in the pictures if you look closely, there is no mention of a power LED indicator in the description. I thought it would be a handy feature. Another thing not mentioned in the description is that the board draws 5mA when nothing is plugged into the USB port. Those observations aside, I just checked that it outputs 5V, which it did.

This is a nice little USB charger. I bought it with a 12v battery that didn't have a charging connector. I installed it in a small plastic earbud box with a battery input plug. The efficiency of this charger meant that the 12V, 3000mAh battery capacity would provide a measured 5V, 5700mAh output from this charger - two full charges for my phone. I use the 12v battery for other purposes too, but this is a nice extra option. If you haven't bought a battery pack yet, you can find some that already
