not 67mm as the picture shown

Hello everyone! I ordered this unit to power my Raspberry Pi + accessories. I haven't done a full test yet, but I don't expect any problems. What I noticed: 1. The size is 64mm x 58mm, not 67mm as shown in the picture.2. The hole spacing is 2.1", the diameter is 6.5mm. These numbers are not shown in the pictures. 3. The output voltage ripple is 50mV (no load). I will update my review after a full test is completed.MJ

Pros
  • The module is waterproof, shockproof, waterproof and more durable
Cons
  • Not sure

EXCELLENT DEVICE - Stable 5V output with variable input/load

This is a great device when You need a constant input In the vehicle I have used some other native circuits and the voltage will always vary slightly with the input voltage. This block is rock solid when measured at various vehicle voltages of 12.5V, 11.8V, 14.4V and 13.5V, this block showed 5.01V at all these voltages and with a variable applied load from 2 -3 And the voltage has not changed. Everyone. A long-term test was carried out while driving a car with a battery voltage in the range of…

Pros
  • Can be widely used in buses, vehicles, large trucks, motors, solar panels, bus and taxi displays, car audio devices
Cons
  • Modern

Rapid failure of power converters

Spent more money because it looked like a quality device and mostly had good reviews. Installed in the glove box of my UTV to power my tablet. On the first ride it did not work for a long time and the tablet died. I noticed that the power supply is not stable. The first email DROK responds with is a request for more information, so I ran a 30 minute test and emailed them a detailed report, but three days later there was no response from them. The voltage gradually drops and does not supply 5…

Pros
  • Slight heat; high transmission efficiency 96% max; Power consumption is about 15mA when idle; uses synchronous rectification technology
Cons
  • Expensive
