Hello everyone,
Since there are more and more needs for mobile internet, I got an idea about mobile router. I have placed many RB951 with USB LTE modem but it is not so mobile, it’s big and it has to be plugged somewhere so my suggestion is to make a small router with integrated battery and LTE interface. Should have not more than 2 LANs and, of course, one USB port to plug the phone to charge the battery. 
Best Regards!
I don’t believe it will be built by mikrotik. But maybe one day after three years we all can be surprised.
Look for TP Link Devices.
You get ones with as big as your hand with 1-3 hour battery backup services.
Wireless tends to be kinda weak on these units though.
The Map2n is pretty close, just add your own battery
Yes, it is but then I should have to take modem and battery… Thats 3 separated parts. 
.
BTW, I know about all other brands who produce this kind of devices… I would like to have mikrotik.
Anyway almost every android phone is able to host the tethering hotspot right out of the box. With battery but without built in ethernets.
Have You ever heard for MiFi router?
Yes. I heard a bit about it. So what?
So, Android phone can’t replace it 100% with functionality. Especially if we consider dataplan for mobile users. Mostly operators offer data card with special pricing which is not able to make phone calls.
Sure you are right. But I don’t believe you can expect such device from mikrotik soon.
Maybe not soon but sure I do expect. Why not? I’ll buy it as soon as they release it.
