Just quick pic I took while un-boxing my Chinese 3G Router for £20 ish from eBay.
It’s described as a 1.8A power bank, 3G hotspot (you provide own 3G stick) & Mini Wifi Access point.
Not bothered too much by the 1.8A battery as have 7a pack, but hope it works on other 2 selling points. Hopefully I’ll report back soon.
