Customer Reviews (4.6 / 5 · 5 reviews)

Mia ★★★★★

Was able to set the output to 12V easily for my LED project, and the boost converter held steady at 0.6A without any overheating. Great little module for the price.

George ★★★★★

Wired this up for a quick 9V output on a small build and it held steady at 0.8A without getting hot. The static draw of around 0.5mAh is practically nothing, so it won’t drain the cell when idle. Exactly what I needed for a compact battery project.

Matthew ★★★★★

Put this together for a portable 12V power bank and the 0.6A max at 12V is perfect for running a small router. The DC-DC boost is surprisingly efficient, and the static drain is so low I don't worry about leaving a cell in it.
