Review on Frienda 10 Pieces MT3608 DC-DC Boost Converter 2A Adjustable Step Up Module - Voltage Regulator Board Input 2V-24V Output 5V-28V (No USB Connector) by Tay Tran

Revainrating 5 out of 5

1/3 works fine so far. The remaining 2 lit up immediately with no load.

Need 10 as 2/3 were bad after unboxing. Smoke immediately. The ones that seem to work fine as long as you keep them under 1 amp. Not sure how they claim more without adding a heatsink or in fast moving air like an RC quadcopter or airplane. Stable output voltage when input signal changes is their good side. Cheap, unreliable parts are the bad side.

Pros
  • Maximum output voltage: 28V; Efficiency: 93% max; Product Size: 36 x 17 x 14mm / 1.42 x 0.67 x 0.55in (L x W x H)
Cons
  • Slightly torn
