We already saw 3 mobile phone brands with basic phones/powerbanks with 5,000 mAh battery but my latest check thru Lazada Philippines just topped them off.
I saw the 3T Mobile F2 Basic Phone and can do as a powerbank with a massive 15,000 mAh battery. The device has 3 SIM card slots plus you can do the basic call and text functions and FM radio as well.
The site also mentioned that it has military grade material but no claims of being as a waterproof handset. The prices are changing from Php 1,400 to Php 1,471. If you are interested to check out this device or to buy, you can check out the source link below
