The OK regulator does the job

Good goods, thank you

Excellent, everything works, connected to the solar panel. The power bank also charges the phone, there is no fast charging))

Smartphones cannot be charged!!! It is suitable for charging lanterns, receivers, power banks.

The board arrived nicely packed, everything works fine.

Everything is whole. There is nothing to check with yet. There are no panels yet.
