Well-built product, easy to install the batteries (18650) everything works well, it automatically changes the current both input and output, on the USB and USB-C ports, the LED flashlight works well too with 4 positions 2 of light and 2 more of intermediate light (SOS) good purchase. The seller delivers what he says. I can't test the DC output for now. But if I can later, I'll add a comment.

Produto bem construído, fácil de instalação das pilhas (18650) tudo funciona bem, automaticamente ele muda a corrente tanto de entrada como de saída, nas portas USB e USB-C , o lanterna de led funciona bem também com 4 posições 2 de luz e mais 2 de luz intermediário (SOS) boa compra. O vendedor cumpre o que diz. Não consigo testar pra já a saída DC . Mas se conseguir depois acrescento um comentário.

The device works very good. _Quick charge output is available only when you have connected only one usb output, otherwise youll get 5V in all usb ports. Quick charge input is possible at 9V._All batteries are connected in parallel so install batteries with similar internal resistance. _Display accuracy is -1%.
