cults3d

This is a marvelous solar power bank. You can bring it everywhere you want without any problem. This tool has 2 features: - torch blade - Solar power bank to charge your phone thanks to USB female connector during the day or the night thanks to the battery. Solar panel will charge the battery during the sunny day. But you can connect directly to the sector via the micro USB (5v max) connector too in order to charge the battery during the night. A blue light indicator is light on when the battery is fully charged. Otherwise a red light indicator is light on. In my test, I only used 1 battery, but the battery connector accept 2 batteries (in this case, batteries are in parallels) Be careful, the power provide by the DC-DC boost converter depends on the model you will choose. And each device to charge requires more or less power, so choose it accordingly. I provide all the necessary componants list, and the assembly diagram (Fritzing format). Dim: 94mm*147mm*40mm
