3D Printed Modular Holder System: USB rechargeable lithium battery pack – 5

Spread the love

A lot of devices are powered by USB, and I think It’s very useful that they become portable, so the solution is to do something like this “Emergency power bank homemade” but more beautiful and integrated.

So I’m going to built a case for the lithium rechargeable battery pack that fit with this modular system.

Here the STL.

Assembly

You need some component, first the tp4056 usb lithium recharging module

Lithium recharging module tp4056 - tp4056 and step-up - Charge disharge USB - Charge disharge

than a step-up module

5v Step-up module AliExpress

than a battery

18650 battery &nbps;AliExpress 18650 3.7v 3400mah

The assembly process is not so simple so I create a short video to explain It.

It should be clear: I do not accept comments on the chosen music: D

Let’s go to use it

As you can see in the video you can use the hot glue to transfer light to the external from the hole to the front, the result becomes like so:

In recharging

Rechargeable battery pack: in recharging
Rechargeable battery pack: in recharging

recharged

Rechargeable battery pack: recharged
Rechargeable battery pack: recharged

And here is the result

Rechargeable battery pack: powers 3W lamp

You can refer to the project of Modular System to check how to use It, like power an esp32-cam or a night/desk lamp.
