1S Modules

Powerbank Modules For Single Batteries

1S Powerbank modules are perfect for beginners and for specialty projects: these modules are designed to be connected to a single battery. No complex battery packs are required.


1S Powerbank modules contain a simple charger to charge a single battery from standard 5V USB power connectors. No complex balancing capabilities are needed.

The modules also contain a boost converter designed to raise the battery voltage of typically 3.5-4.2V to 5V USB or more.

Solar Powerbanks

1S Powerbank modules are perfect for small solar-powered powerbank projects. Simple solar chargers use a single battery to buffer energy. By connecting a 1S Powerbank module to this buffer battery, you can conveniently charge USB devices off your solar panel.


Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.

Here is how your comments are stored

Whenever you leave a comment, a new github issue is created on your behalf.

  • All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.

  • There is no third-party provider, no disrupting ads, and everything remains transparent inside github.

Github Users Yes, Spammers No

To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.

If you don’t have a github account yet, go get yourself one - it’s free and simple.

If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.


For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
