Introduction: The "sweet" DIY Powerbank

Picture of The "sweet" DIY Powerbank

Hello everyone, as my first instructable, I've created a tiny powerbank, entirely made using recycled parts.

Let's see how it's made!!

Step 1: Parts and Tools

You'll need just few things:

- a DC to DC module

- a big pack of Tic-Tac

- a battery (I used the one of an old useless Samsung phone)

- some wire to solder

- a welder pyrography

Step 2: Prepare Your Stuff

Now, you just have to follow this simple steps:

1) CUT THE WIRE: you'll need just few centimeters (or inches - hello America!!) of wire. Be sure not to use too much wire or you'll have troubles positioning everything inside the box

2) SOLDER: please make sure to solder the anode of the battery to the anode of the DC-DC (the same goes for the cathode) or your project's going to end up dead. In the pictures I highlighted them so you can distinguish them better

3) PUT THE BATTERY UNDER THE DC-DC: that's right. If you want your powerbank to fit inside the Tic-Tac box, you need to do this. Furthermore you may want to ensure the battery to the DC-DC using just a bit of black tape

Step 3: Prepare the Box

This one might start as the sweetest step ever. Why? Because you've got to empty the Tic-Tac box, so.. EAT THEM ALL!!!! I suggest you so to pick your favourite flavour, and maybe enjoy them while making this project.

Once empty, you need to cut the long side of the box, so you can easily plug your USB cable. I did this using the same welder pyrography I used to connect the battery to the DC-DC module, but in this case I replaced the soldering tip with a cutting tip. Anyway you can use a Dremel or other tools you like (just be VERY careful not to cut yourself) cause the plastic is very soft.

Step 4: Place the Powerbank Inside the Box and Use It

This is the final step: before putting your powerbank inside the already-cut box, you may want to put some double sided tape to the battery in order to firmly attach it to the wall of the box.

THAT'S IT, YOU FINALLY MADE IT. BRAVO!!!!

If want to charge your battery (like I did), now you can. Or either way, if want to charge your device, you can too.

HAVE FUN!!!!

Hey, thank you for the nice and sweet DIY! I'' pretty much a noob in electronics but I have to ask: Can this be done with AA batteries instead? Chargable ones of course. Also do these leds have a color code for when the battery is empty/full? Thanks!

Hello e_Samurai, thank you for asking. About the batteries, of course you can, you just have to solder them in parallel in first place(every + to + and every - to -). I suggest you though to add another DC-DC power module in order to not overpower the circuit (you have to set the module to the level of voltage required). About the leds, they indicate the level of charge/discharge of the battery, but not every module's got it. So if you want the exact one that I used, just look for it. I hope you'll have fun like I had!!

you should have called it a tik tak power pack lol awesome build man?

ignore the question mark

Ahahahah you're right man!! Thank you :D

How do you charge your Samsung battery? Is it pat of the dc converter circuitry? Thanks

fabby1 (author)lazer5582016-09-30

Yes, as you can see in the picture, my module' got two USB ports as output (one is 1A and the other 2A), and a microUSB port as input

lazer558 (author)fabby12016-10-01

Ok. Thanks. I missed that. For anyone else under the led between the usb ports.

Since you are using a DC-to-DC module rather than a LiPo charging module, I suspect that you are damaging your battery every time you charge it. If the charging circuit does not cut back to a trickle when the battery is fully charged, the battery will be damaged.

It comes from another donor powerbank, so honestly I'm pretty sure that it won't cause damages. Anyway I'll let you know if something happens, besides that this battery is "expendable"

Hello NearlyWitty and lazer558, this battery can be charged using a phone carger (the brand doesn't matter, nowadays smartphones and tablets use the same voltage), plugging a USB cable to your SmartTv, computer or whatsoever. Personally I charge it using a solar panel, even if it's a really slow process. Anyway, if you're interested, a solar powerbank is my next instructable (I think maybe in a couple or more weeks, depending on my duties), so you'd better stay tuned. Thank you guys!!
