Hello,

I made an external battery to keep a lot of enery during your trip.

My phone use induction system, so I added from an basic station (I used the cheaper one found on Amazon) and added two 18650 battery (more common) with a Lithium Battery Charge Shield Board.

At the end, you can use USB-C or micro USB as input for charging and use 2 x USB-A or induction for recharge your devices.

I designed with different levels, so if you want you can edit my design here

I used different colors, specially a transparent one to keep light from Leds.

You don't need a AMS system, you can print separately if you prefer.

Materials:

• 2x18650 battery
• 1x18650 Lithium Battery Charge Shield Board (AliExpress)
• Induction charge : (Amazon)
• 4xM3*16 screw
• 2 wires (you need to connect battery shield with induction)

Have fun,
