More Power Save Power Bank Long Life 24 hours Working

In Day to Day Life Power bank is Need for in (offices,works,tours,etc..) even the Power banks have just
20000mah but since it is for only two phones can chargerd full ,So We devolped an new item
just 12 v 7.5 ah battery to 70000mah powerfull to charge 20 phones in 24 hours

Items is Need for Making

1. 12v 7.5 ah battery
2. Switch
3. A Car MobileCharger Board 

Just 3 items to get more Powerfull......

Zener Diode Voltage Reference

Item For Need

1. 6vZender
2. 1uf cappacitor
3. 1k resistor

Diode Turn off Timmer

Item Need For

1. 2ohms resistor
2. 1N4007 Diode

Dc Generator

Make A Power Loss Dc Generator

Items For Need

1. Dc -Dc Stepup Transformer
2. Dc motor 9v-2
3. 1k resistor
4. LT1070   -1 
5. Relay
6.  10v DC battery
7. Switch -1

On Working
Switch on the dc voltage in battery to dc motor act as a Generator then the generated voltage incress as 23v
then 10v goes to motor and 12v get back..
If it does not work change the battery voltage
