Review on π Efficient Solar Charge Controller: PowMr 20A Solar Panel Battery Controller with Dual USB, LCD Display, Timer Setting, and Adjustable Parameters by Rich Montgomery
It works, but the membrane has never stuck.
Works. Looks awful and I don't know how long it will last. The membrane keyboard has never been pressed firmly against the device and is constantly peeling off. Let's see how long the keys hold up. This also likely provides a path for moisture and dirt to enter the device.
Pros
- Easy to install
Cons
- Slightly wrinkled
