Customer Reviews (4.6 / 5 · 5 reviews)

Riley H. ★★★★★

The packaging is sturdy and clearly labeled, so I can grab the right voltage without hunting through my drawer. Having all nine fixed values in one kit saves me from ordering singles every time I prototype a new supply.

Ryan J. ★★★★★

The set includes all the common fixed voltages from 5V to 24V, so I’ve got exactly what I need for bench work. One of the 7812s I tested held steady at 11.98V under load, which is right on spec.

Lucy ★★★★★

Was able to quickly swap out a failed 7805 in my bench supply with one from this assortment — the voltage held perfectly stable under load. Handy having nine different values ready to go without ordering singles.
