Great portable Micro Solder Joint Iron
This is a great good quality soldering iron for portable or field use! FIRST! Make sure you are looking for the right Soldering Iron (This review is for the HS-02B Micro Soldering Iron) HS-02A For General Purpose Medium Size Tip Soldering including Wire terminals, Switches, Large Components, etc. HS-02B For Small Component Soldering (i.e. on PCB Boards) ... If you need a microscope while soldering then this is the one! The main difference is the size of the Soldering tips which are NOT interchangeable between the two Iron Handles. What makes this a better Soldering Iron? 1. FAST, SAFE and EFFICIENT: It heats up within a few seconds to an accurate set-point temperature. Using the new USB-C Power Standard, the iron can supply up to 100W for fast heatup automatically and yet it uses only about 4W for 370C steady state tip temperature (see Photo). User can select Sleep and Standby times for as little as 1 minute with a standby temperature as low as 100C (see Photo). 2. PORTABLE: Using the supplied C2-to-C2 USB Cable it can be plugged in to a AC outlet or 12V DC C2 USB power source. The handle is compact and can be used in tight spaces. The supplied cable is sturdy and can handle up to 100W but is very flexible to facilitate handling the iron (see Photo). 3. USER FRIENDLY: the display and user buttons allow you to quickly set and confirm the best soldering temperatures (3 adjustable pre-set values to accommodate Lead-Based and Lead-Free solder along with quick up/down temperature tweaking). A brief summary of Soldering Iron choices (for Soldering wires and electronics): 1. AC Outlet old-style "Dumb" IRON: Takes minutes to heat up and stays hot. Tip will oxidize if left on. Cheap. 2. AC Outlet IRON with adjustable Temperature and Display and ESD Safe: Takes multiple seconds to heat up and goes into standby mode to prevent Tip Oxidation. 3. Butane Portable Soldering Iron: Fast heating iron for portable use. Crude temperature control but can maintain tip temperature with large thermal loads (Large wires, connectors). 4. New Generation USB C2 Irons: Very fast heatup, accurate temperature regulation and display, compact. Accurate temperature regulation minimizes component overheat damage yet can supply up to 100W to maintain temperature to ensure a good solder joint.

High quality, high grade, powerful portable soldering set.
If you're in the market for a small soldering iron, Look no further. Get this. having owned multiple soldering irons, both electric and butane powered, from established home improvement brands and hobbyist stores, I was extremely surprised that this small soldering pen easily best them all In every way. Size and form factor, rate of heat Maximum temperature, precision, ease of use and presets, and included accessories. The device looks and feels well made and solid, powered by a 100W USB-C power supply that also fast charges my phone and can do so while powering the iron thanks to the (2) USB-C and (1) USB-A 3.1 power output ports. The carrying case is small yet holds the soldering iron, with room for all three included iron tips, straight point, angled and flat blade, one in the iron and the other two in their protective hard sleeves, the iron tip itself is protected with a cap that twists on, nearly eliminating the possibility of the cap falling off on its own with a hot tip exposed to damage or potential burns. The USB-C cable included is solidly made with a silicone jacket and is extremely flexible with quality feeling metal connectors. A small iron stand and thin piece of sponge are also included in the case. The tips push straight into the unit and are securely held in place no need to twist or tighten anything. Upon sensing the presence of a tip the iron temp can be set manually, or to any one of three preset temperatures, which you can select in the settings, to have easy access to your most frequently used temperatures for the type of work you do. The screen is bright and easy to read, and silicone grip near the tip of the iron makes it comfortable to hold to solder precise joints. With other soldering irons I sometimes ran into issues of the tip not heating up enough but that has never been the case here. I always have enough heat to melt any gauge solder exactly where I want it for perfect connections in my electronics and metal connections. For everything except the largest of soldering jobs, this is the only one you'll need. Highly recommended.

Item as described! SUPER fast shipping!
Item as described! Super Fast Shipping! Minor cord and power supply problems. Just reverse the cord. Otherwise I have read if it is the power supply, they will happily replace it. Great IRON! Super Easy to use. Portable! Tips are great quality! Functionality is great! I use it for most of my micro soddering!

Lovely, but Case too Small for Power Supply
Fantastic soldering iron with a great tip selection, maneuverable size, and battery life. While it's relatively easy to use, there are some minor annoyances, such as constant beeping when the tip is out while plugged in, even when in standby mode. That's dumb. I also wish the case was large enough to fit the power supply, and that the cord was another 1-2' longer and more pliable. Overall, great functionality and utility for what it is though.

Very nice iron! EXTREMELY FAST heat up even at 20% power output! Super simple and easy to use menu and temp setting. 3 adjustable presets. Accepts input voltage from 9v to 20v on USBC. Comes with dc barrel jack adapter, 3 different soldering tip cartridges, 100w usbc power cord (highest quality USBC charger I've EVER SEEN!!!! By a landslide!!) adjustable volume and brightness. Solid feeling buttons, it delivers the heat when it's needed and rests when it's not needed. ABSOLUTELY WORTH THE PRICE!! YOU WONT GET ANYTHING BETTER!!!! (even if you throw more money at it!!) The included case has enough room for everything except the power block for the wall. It has enough room to store a roll or two of solder in there as well as the spare tips and whatever little accessories you need!

******POWER SUPPLY IS US************ ALSO I THINK ITS FUALTY, I tied two US-IK adapters, and it wouldnt work with either. It works fine with an apple macbook charger. Despite this, I think I'll keep it.
