Universal mobile keyboard won't work

Make sure your mobile power bank is always turned on, in fact, if you stop entering any words via the product for a while, the major of mobile power bank will turned off because of its power-saving design.

I know, it's so insulting isn't it?

One Amazon reviewer opened up his faulty unit, and found that the battery is fine but the power socket is badly soldered on.

So it appears to be a manufacturing problem/design flaw with the power socket. Possibly just one batch, although considering this thread is now over a year old and has multiple people experiencing the same problem over that time, I'm going with a design flaw that potentially affects all these keyboards.

Time for a recall and apology Microsoft, not time for insulting us with nonsense replies.

I'm waiting.

I have the same issue. I bought at a trusted partner, Challenger for a 103 SGD. I didnt realise the issue when i first use it with charging port. It wasnt until i prepared to bring it out that i realised it didnt work without charging port. Brought it to the shop, asked me to find the service center. Service center opened on office hour. Lucky that i never went as i **** preparing to go after work or weekends. Phone line doesnt work and hotline available on office hours. Got help from challenger to contact them. Asked me to register to microsoft website. Need 5 working days to confirm my purchase. Now, its more than a week. No reply from Microsoft. No call, no email. I am really disappointed. I shouldnt have chose this product. Such quality at such a price. Should i use my annual leave just to get this keyboard fixed?

I will take this as a lesson. If the problem cant be solved, it comes from top to bottom of microsoft. I will be a fool for supporting microsoft and will be the last of microsoft product i will ever buy.

Both way doesn't turn on after charged. It worked only when it was connected to a charging port.
