Miniware has simply launched their newest precision soldering iron, the TS21. It’s designed for makers, hobbyists, and professionals who need a compact, transportable soldering answer. On this evaluate, I’ll stroll you thru the options, efficiency, and my total impressions of the TS21 — and whether or not it’s an excellent match for FPV drone constructing and repairs.

The place to Purchase
Get the TS21 soldering iron from:
Within the field, you’ll discover:
- The soldering iron physique
- A soldering tip (the TS21-KU blade tip)
- A set of coloured heatshrinks for the deal with
- A guide
Design and Construct
Proper out of the field, the TS21 feels premium. The aluminum alloy physique provides it a strong, sturdy really feel.
It’s noticeably extra compact in comparison with older fashions just like the TS80 or TS101, making it the smallest Miniware soldering iron thus far. Regardless of its compact dimension, it weighs about the identical because the TS100 and TS101 — nonetheless mild sufficient for precision work.
The design is modern and practical:
- OLED Show: A vivid 0.91-inch display reveals temperature, modes, and menu choices.
- Controls: Two buttons on the physique for fast changes and navigation.
The soldering ideas are smaller in diameter than these used on the TS80 or TS101. They slide in and lock with a easy click on, making tip adjustments quick and safe.
Once I first opened the field, I used to be a bit puzzled by the coloured heatshrinks — till I spotted they’re meant as anti-slip grips for the deal with. You may shrink one onto the physique with a scorching air gun for higher consolation and a customized look. Truthfully, they’re elective — I’d solely trouble if sweaty fingers are a difficulty for you.
Lastly, the USB-C energy port is positioned on the finish of the iron. It helps 18–100W USB-C PD adapters, which means you’ll be able to run it off a high-power wall charger or perhaps a PD-compatible energy financial institution.
Options and Settings
Like different Miniware soldering irons, the TS21 comes with a settings menu that you may navigate with the 2 buttons.
A few of the key adjustable parameters embrace:
- Sleep mode timer
- Sleep temperature
- Working temperature
- Most energy
The menu is intuitive and the buttons are responsive, making it easy to function. The show additionally has auto-rotation, so the display orientation immediately flips relying on which approach you maintain the iron.
One function I notably love is the temperature presets. You may set three customized temps and cycle by way of them immediately with a single click on of the button. I’ve mine set at 450°C, 400°C, and 350°C for various jobs, which saves a ton of time in comparison with holding the button down a number of clicks simply to regulate.
There’s additionally a built-in LED mild close to the tip that lights up your workspace. It’s surprisingly helpful when soldering in low mild or tight areas.
The sleep mode works completely too — when the iron rests in its stand, it mechanically lowers the temperature, serving to protect tip life and save energy.
Right here’s the guide.
Efficiency Testing: Blazing Quick Heating
The heating pace of the TS21 blew me away. In my assessments, it hit 450°C in below 5 seconds! That’s insane. For comparability, TS100 takes 13 seconds whereas the HGLRC RC2 takes 11 seconds.
This pace is partly as a result of smaller soldering tip — much less mass means much less vitality required to warmth it up. The upside is that it additionally cools down extraordinarily shortly, reaching decrease temperatures in simply a few seconds.
Mixed with the presets, this makes switching temps for various duties almost seamless.
Downsides: Small Tip Measurement
The compact tip has an enormous draw back: it struggles with massive solder joints that demand extra warmth. For instance, when soldering an XT60 connector to a 4in1 ESC, I discovered myself holding the wires down for too lengthy, which overheated the pad and virtually burned my fingers. Not ultimate for giant jobs.
I actually want Miniware supplied bigger ideas for the TS21. Because it stands, it’s unbelievable for micro drones (3-inch and smaller, together with tiny whoops), however the tiny tip may wrestle when engaged on heavy-duty builds like 5-inch and 7-inch quads with thick XT60 wires and high-current ESCs with great amount of copper traces.
Energy Consumption
One other remark: despite the fact that I set the TS21’s most energy to 100W, it not often got here shut. Utilizing a 100W PD energy financial institution, I monitored real-time utilization and usually noticed 50–60W, even throughout preliminary heat-up that usually makes use of essentially the most energy. It nonetheless feels lots highly effective, nevertheless it’s value noting in case you anticipated it to constantly draw 80–100W.
Different Soldering Iron Ideas
My TS21 got here with two further cone needle ideas, that are clearly designed for precision work. Personally, I discover the inventory blade tip wonderful for FPV builds — it strikes the precise steadiness between precision and the power to deal with reasonably massive joints. Except you do extraordinarily effective electronics work, there’s little have to swap ideas. That stated, I do want bigger ideas have been obtainable.
Additionally notice that the TS21 ideas are noticeably smaller than these utilized by the TS100 or TS101, and sadly, they’re not cross-compatible. You’ll want ideas particularly designed for the TS21.
Is It Superb for FPV Pilots?
The TS21’s light-weight design, fast heating, and built-in LED mild make it a pleasure to make use of. Swapping ideas is fast and painless, and the compact dimension makes it simple to retailer and transport. For fast discipline repairs, FPV drone builds, or delicate electronics, it’s a really succesful and versatile iron.
Nonetheless, there’s one downside: the TS21 solely accepts USB-C enter. In contrast to widespread fashions such because the TS100, TS101, or HGLRC RC2 — which may be powered immediately from a LiPo battery — the TS21 requires both a USB-C energy financial institution (at the very least 100W) or a LiPo-to-USB-C adapter. This makes it barely much less versatile within the discipline.

Remaining Ideas
The Miniware TS21 is a wonderful transportable soldering iron that delivers insanely quick heating, a 450°C max temperature, and considerate options like sleep mode and an LED work mild. Whereas it’s not designed particularly for FPV, its compact kind issue and reliability make it a robust possibility for discipline repairs and micro drone builds.
That stated, the tiny tip dimension means it might wrestle with bigger solder joints like XT60 connectors and high-current ESC energy pads. For these jobs, irons just like the TS101 or HGLRC RC2 are extra versatile selections:
For bench work, I like to recommend a correct soldering station just like the AiXun T3A, which is at the moment my day by day driver: https://oscarliang.com/aixun-t3a-soldering-station/
