A Power Bank For Soldering On The Go

If you have a portable gadget, the chances are you’ve probably used power banks before. What few could have predicted when these portable battery packs first started cropping up is that they would one day be used to power soldering irons. Dissatisfied with the options currently available on the market, [Franci] writes in with his own power bank specifically designed for use with his TS80 portable soldering iron.

The electronics side of this build is simple and easy to replicate, with 4 18650 Li-ion cells standard to most high-capacity power banks and an off-the-shelf Fast Charge module serving as the brains of the operation. The beauty of this project however lies in the design of the actual case, completely custom-made from scratch to be 3d printed.

Unlike most power banks, where the outputs stick out to the side and leave the connectors prone to being bumped and damaged, [Franci] engineered his case so the ports are stacked on top and facing inwards. That way, USB plugs are contained within the footprint of the power bank’s body, and therefore protected from bending or snapping off in the socket. He also gracefully provides all instructions needed to make your own, including a wiring guide and a reminder about safety when dealing with battery packs.

If you’re unfamiliar with the TS80 soldering iron, we’ve featured the younger sibling of the TS100 in a previous post. And if you think this power bank is too simple for you, don’t worry, we’ve got you covered.

A Sneak Peek At The TS100 Soldering Iron’s Younger Sibling

Many readers will be familiar with the TS100 soldering iron, a lightweight and powerful tool with an integrated temperature controller in its handle based upon an STM32 microcontroller. As an iron it’s a joy to use, it has hackable code, and it has become a firm favourite within our community. There have been rumours of a TS100 stablemate for some time now, with the model number being touted as a TS200 and with it being said to be USB-C powered. But beyond those tidbits, until now there has been not a lot to go on.

So [Marco Reps]’ video that we’ve placed below the break is a particularly interesting one, featuring as it does a prototype of the iron in question. It’s called the TS80 but there is evidence on its PCB that it has held the TS200 moniker in the past, it’s USB-C powered, and it features a new integrated heating element and bit with a Weller-style 3.5mm jack connector.

He runs it through a battery of tests and finds it to perform very well indeed, sometimes better than the TS100 despite his not having a USB-C power source capable of supplying the same voltage that his TS100 gets through its DC jack. To be clear, the TS100 is still a very good iron indeed, this one is simply a little bit better. Inside a sturdier metal barrel is a PCB with the STM32 on board as well as an OLED display that looks a little smaller than the one on the TS100. The shorter element receives praise, while the TS100 is hardly a long iron it is always good to get as close to the action as possible.

There is a concern over the lack of a DC jack and its reliance on USB-C, though he points out that with the appropriate cables and increasing USB-C adoption this should not remain a problem for long. We’d be interested to ensure that it can be powered through the USB-C socket from a simple DC power source such as a battery though, as that flexibility is such a bonus with the TS100.

So then, the TS80 is coming, but the TS100 is still a very good iron indeed so there’s no need to throw yours away any time soon. It’s an iron we look forward to seeing when it arrives though, and no doubt we’ll give you our verdict.

You can see our TS100 review if that takes your fancy, and while you’re at it take a look at one of the community’s most awesome TS100 hacks. [Marco] muses on how long it’ll be before someone has their TS80 playing audio through that 3.5mm jack.
