BEBEBAO Electric Breast Pump HOW TO Unbox/Assemble/Use 

El mío se quedó sin batería y no carga alguien sabe porque? O que hacer

So I just got mine, I’ve used it 2 times now when I try to turn it on I get -4 50 20... what does this mean?

I don't know what I am doing wrong. I would think that being plugged in to the electricity it will be charged or work and it doesn't. Is supper weird, it works whenever it wants, is so inconvenient. DISLIKE IT!!!

Its cell colour green...but when i switch off charging usb...it turned red

Its battery time?

Sure

How much is the cost of this please let me know

Is it battery operated?
