TS101 Portable Soldering Iron Review: Is It the Best First Iron for Developers Getting Into Hardware?
TS101 Portable Soldering Iron Review: Is It the Best First Iron for Developers Getting Into Hardware?
The short answer: yes, for most people coming from software to hardware, the TS101 is an excellent first soldering iron. It heats up in under 10 seconds, runs from a USB-C PD source you probably already own, and gives you real temperature feedback without burying you in a confusing interface. It is not perfect, and there are worthy alternatives depending on your budget and use case. But if you want one iron to learn on, travel with, and actually trust, the TS101 earns its place on the bench.
This review covers the TS101 portable soldering iron from the perspective of someone who writes more code than schematic diagrams. The goal is not to evaluate it against professional rework stations. The goal is to answer whether it makes the jump from blinking LEDs in a simulator to soldering your first real PCB feel approachable rather than intimidating.

TS101 Soldering Iron: Quick Specs at a Glance
Before getting into the feel of using it, here is what you are actually buying. The TS101 is a smart, USB-C powered soldering iron made by SEQURE. It uses a PD (Power Delivery) negotiation chip to draw up to 65W from a compatible charger, and it stores temperature profiles and settings in onboard memory so your preferences persist between sessions.
| Spec | Detail |
|---|---|
| Manufacturer | SEQURE |
| Power Input | USB-C PD, up to 65W (20V @ 3.25A) |
| Also Compatible With | DC 5.5mm barrel jack, 12V to 24V |
| Temperature Range | 100°C to 400°C (212°F to 752°F) |
| Thermal Recovery | Fast, approximately 4 to 8 seconds to target temp from cold |
| Tip Standard | TS-B2 compatible (wide ecosystem) |
| Display | OLED, shows live temp, set temp, wattage |
| Weight | ~33g without cable |
| Firmware | Updatable via USB |
| Idle Shutoff | Configurable, motion-triggered sleep |
| Body Material | Aluminum alloy |
The TS-B2 tip compatibility is worth calling out specifically. It shares a tip ecosystem with the older TS100, which means a large supply of aftermarket and specialty tips (chisel, knife, fine point, hoof) is available, usually for a few dollars each. You are not locked into proprietary consumables.
What the TS101 Soldering Iron Does Well
Heat-Up Time That Doesn't Test Your Patience
From a cold start to 320°C (a reasonable lead-free solder temperature) takes about 8 to 10 seconds with a 65W USB-C PD charger. This matters more than it sounds. One of the habits that leads to bad solder joints in beginners is reaching for the iron before it is fully ready, or leaving it on for hours to avoid waiting. A fast heat-up time means you turn it on, load your project, and it is ready before you have even oriented the board.
At lower wattage, say 45W from a laptop charger, heat-up time stretches to around 15 to 20 seconds. Still completely usable, just worth knowing that what charger you use is not trivial.
The OLED Display Gives You Real Feedback
The small OLED screen on the body shows three things in real time: your target temperature, the actual tip temperature, and the wattage being drawn. For a beginner, this is genuinely educational. You can watch the wattage spike when you touch a thermal pad and drop when the joint reaches equilibrium. You learn to read the iron's behavior rather than guessing at it.
Temperature adjustment is done with two buttons. Hold one to enter the settings menu, tap to step through values. It is not the fastest interface, but it is clear, and you never accidentally change settings mid-session because the button travel is distinct.
USB-C PD Means You Already Have a Compatible Charger
If you own a modern laptop, you almost certainly own a 45W or 65W USB-C PD charger. That is the same charger that powers the TS101. This removes one barrier for people who are just getting started and do not want to invest in a full bench power supply immediately. A 65W GaN charger (which runs around $20 to $30) is all you need to get the full performance out of this iron.
The barrel jack input also means you can run it from a bench supply or a 12V battery if you are working away from a wall outlet entirely. This dual-input design is quietly practical.
Firmware You Can Actually Update
The TS101 runs updatable firmware, and SEQURE releases updates that have improved temperature accuracy, added display modes, and refined the power negotiation behavior. You update it by connecting to a computer over USB, downloading the firmware file, and copying it to the device, which appears as a mass storage device. If you have ever flashed a microcontroller, this will feel familiar. The process takes about two minutes.
Tip Selection Is Practical and Affordable
The iron ships with a fine conical tip, which is fine for through-hole work but limiting for surface-mount. A TS-B2 chisel tip (also called a bevel tip) in the 2mm to 3mm range is almost always a better starting point for general electronics work because the larger contact area transfers heat more efficiently. These tips cost roughly $3 to $6 each from reputable suppliers. Buying a small set of three to four different profiles when you buy the iron is a sensible move. [LINK: ts-b2-tip-set]
What the TS101 Doesn't Do Well
The Grip Divides People
The TS101's aluminum body is cylindrical and relatively slim. Some people find this comfortable and precise. Others, especially those used to holding a pen with a fatter grip, find it tiring over longer sessions. There is no rubberized section or ergonomic contouring. If you are planning to solder for more than 30 to 45 minutes in a single sitting, this is worth thinking about. Aftermarket silicone grip sleeves exist and cost almost nothing, but it is an extra step.
The Cable Can Be Awkward
The USB-C cable connects at the back of the iron and can tug against your hand depending on how your workspace is set up. The ideal setup has the cable running away from you and slightly elevated, which usually means clipping it or routing it through something. Some users switch to a coiled USB-C cable, which helps significantly. This is a minor complaint, but it is worth knowing before you start a frustrating first session.
No Soldering Stand in the Box
The TS101 does not ship with a stand. An iron that reaches 400°C sitting on your desk is a problem. You will need to buy or make a stand separately. There are TS100 and TS101 compatible brass wool tip cleaners with integrated holders that run about $8 to $15 and work well. Do not skip this. [LINK: soldering-iron-stand-brass-cleaner]
No Built-In Accelerometer (Compared to Newer Competitors)
The TS101 uses a tilt sensor for its sleep mode rather than a full accelerometer. In practice this works fine, but the Pinecil V2 (its main competitor) uses an accelerometer that is more sensitive and reliable for detecting when the iron is resting versus in use. The difference is small day to day, but it is a real one.
Who the TS101 Is For
The TS101 is a strong match for a specific type of builder: someone who primarily works at a desk, solders a few times a week rather than all day professionally, wants decent temperature feedback and control, and values portability because they sometimes work from a laptop bag setup, a kitchen table, or a friend's workspace.
If you are a software developer building your first hardware projects, assembling kits, soldering headers onto dev boards, building mechanical keyboard PCBs, or putting together simple home automation sensor nodes, this iron will handle all of that comfortably. The learning curve is low because the interface is readable and the behavior is predictable.
It is probably not the right tool if you are doing heavy desoldering work, reworking large QFP packages regularly, or soldering in a professional production context. Those use cases ask for a full station with a strong pump, fume management, and more tip mass.
