In this video I will show you the ultimate solution to power on the go. This DIY power bank features a removable battery pack, which can be easily replaced, giving this power bank unlimited capacity as long as you have enough cells. The cost of the row components of this power bank is around 60 dollars, which is two times cheaper than anything commercially equivalent. WARNING: Do everything at your own risk, lithium batteries can catch fire or explode if mishandled. This power bank requires a more than a basic understanding of electronic to complete.
