Your iPhone may be powerful but it doesn’t have unlimited battery life. Investing in a decent power bank enables you to use your device longer. The BT-20 Wingman is a tactical power bank with detachable batteries and 20W Type-C output. It can use 21700 and 18650 flat top batteries. It has a RGB battery meter that shows battery level automatically.
The BT-20 weighs only 38g. It is about the size of a credit card, so you can easily fit it in your pocket. It comes with smart temperature control and reverse polarity protection. You can find this project on Kickstarter.
