Cantidad aceptable por el precio
La verdad no encontraba este articulo por ningún lado, era para un proyecto de ciencias de mi sobrina, y el precio por la cantidad que enviaron me parece super, muy recomendado.

Great, but specs not included on each component board.
These are awesome, thank you. I made it 4 stars instead of 5 due to specs not being written on the components. I don't know how many amps are outgoing/incoming, I had to decipher the status light myself, no instructions. But...it works great! I've installed little batteries in my TV remote controls and included this USB option so I never have to replace the batteries..I just plug it in the MicroUsb and charge my remotes that way...and I can plug a little light into the output usb port for light at night while watching tv... anyway, fantastic...it doesnt need instructions, but it would have been nice to have the specs engraved onto each component.

Best chargers I've tried so far
These do what they say, they charge the battery and your device.

Some of them work OK. Half were non functional out of the package.
The units that are functioning seem to work Ok. About half of them were defective straight out of the package. There is a tiny transformer on the board that apparently gets easily damaged during shipment. I noticed on the boards that did not work that they got extremely hot and a couple of them were obviously broken. For the price they're OK. Just be prepared to have a few duds.

Drop out voltage
I really like the device it takes the voltage from my Li-ion 18650 cells which is from 3-4.2 volts and boosts it to 5v for use out of the USB plug. The only thing I can't understand is once the cells get to 3.1 volts the power out of the USB connector goes to zero. I recharge the cells but disconnecting the load from this device is required to have it come back online.
