The product comes in antistatic bags. I tested all three of them and work perfect! I connected in 12V to 15V DC Power Supply as Input Source, I’ adjusted for 5V Output and connected in 2.2A load. Works Very Good, I measure a little bit of noise (20 – 35 mVpp) in the Output but this is right for this switch type converters. Quick tip: connect an Inductor same type as that who is mounted in the board in series with the (+) of output, and then connect a couple of capacitors (one 100uF Electrolytic and one 100n Ceramic) between the free leg of Inductor and the GND. THAT’S IT NOISE NO MORE!!! I use the module and the low-pass Filter to supply +5V to an RTL-SDR and a Wide Band Preamplifier for HF Band, and the result it’s GREAT! Seller’s service was VERY GOOD!!! Delivery Time its fast. TOTALLY RECOMMENDED!!!

I tested it with a 12Vdc power source and all the 3 power supply circuits work like a charm. the voltage adjustment is easy. satisfied and suggested ho testato i 3 circuiti con una sorgente a 12Vdc e tutti e 3 hanno funzionato perfettamente. la regolazione con trim multigiri è OK. soddisfatto e suggerito come acquisto

Very stable and precisely adjustable DC convector. the best I've ever used.

Fast shipping and delivery, as usual with orders at Banggood. I ordered these 3 items pack and recieved the package in good shape. All 3 items are OK. I tested 2 of them and they operate just fine. Good PCB and quality. The small size make this DC-DC converter ideal for a lot of electronic projects. Satisfied and recommended !!!

This step down converter has very good efficiency! Compared to other products rated at "3 to 4 amp" this has 92% efficiency (the weaker ones with LM2496 only get 81%). Tested using 10,5 Volt input and 7 Volt output at 1.93 amps. You can see in the picture it has plenty of room for more power as it is not getting very hot even without any heat sink or moving air.

One in three does not work. the circuit of this one is different from the other two as shown in the second image. I needed three functional ones.

Fonctionne très bien pour une tension de 12V avec un accu lipo 3s.
