How to Make 220V Power Bank with Old Laptop Battery 

With li ion batteries model 18650, three important things are considered: 1) model 18650, 2) voltage 3.7V, 3) capacity (battery capacity is expressed in mAh)

First of all you should not solder the battery. Second you should check the capacity of the battery to make sure the cell is equivalent to each other. Anyway its nice videos

10:15 - 10:29 aa gya swad...!😂😂 Half Brick made by nokia..

using recycled cells like that without regard to their capacities is a sure way to start an electric fire.

Excelente proyecto y estupendo resultado obtenido de la fabricacion, de banco de energía de 220 V con una batería vieja para computadora portátil, respetos y saludos desde Venezuela.💯💯💯💯👍👍👍👍👍🤘🤘🤘🤘🙏🙏💯💯💯💯

Excellent, thanks.

I like your editing

Nice, but every thing with out calculations, battery charger for cell require 12.6 v for 100% charge, not calculated cell MAh batter used same mah, not included safety circuits spatially over heating, must b included volt and amp meter. But good 👍

OMG Don't use solder on 18650 batteries it will nearly destroy them Use SPOT WELDING.

1200w inverter . But inside😂😂😂😂😂 250w 😂😂😂😂😂😂😁

Soldering is not a good idea for li-ion battery's

bad work、

First of all no safety like the batteries are soldered together which is highly dangerous and then there is not coverages to the batter he just used normal flammable plastics and then he uses a square wave inverter which is not suitable for smart devices like phone chargers and etc. so please do not repeat this project guys it’s really not safe and he makes money of out this useless video
