Before I bought it, I looked for this specific product on YouTube, I only heard positive things about it so I decided to buy it, and it really is excellent, I don't think I could hold another soldering iron in my hands, it is so fast in the temperatures it can rise and drop, that you say okay it's incredible, as for its weight it feels like it’s not even there in your hand, today as soon as I got it in my hands, I started testing it on various soldering tasks, whether on SMD or with regular capacitors and various others, and I only have positive things to say about this one, I haven't seen any negatives for now but if I happen to spot something, I will come back to write it.

Perfect. It’s great for very detailed work, and if you also have good solder, you can do whatever you want, even if you’re inexperienced.

The temperature is adjusted directly. No more waiting 5+ minutes every time for it to heat up, and just as long for it to cool down. It also seems that adjusting the temperature depending on what you’re doing matters.

The stand it comes with is useful, and the best thing about it is the sleep mode... when you put it in the stand, it stops heating, and when you take it out, it heats up within 2–3 seconds. I wouldn’t buy a soldering iron without this feature now that I have this one.

The soldering iron is as lightweight as can be. It feels completely hollow inside.

The cable is 1.4 m, so let’s say 1.60 m including the soldering iron and tip. It would be good if the cable were longer. You can also get a Type-C-to-Type-C extension cable (at least €6.50 for a 2-meter cable)... to make the cable longer instead of using an extension cord, which is much bulkier and heavier, and also dragging the power supply along with it, which plugs in after the extension cord rather than before it. Otherwise, you can get a 5-meter two-pin extension cord, which costs me €3–4.

The soldering iron draws at most 20 W... I measured it with a meter, and the highest reading I saw was 15 W at 412 degrees... so I don’t know what the 110 W it says means; presumably it refers to its power compared to ordinary AC soldering irons... Anyway, in general, at 350 degrees it draws only 6 W... and when you put it in the stand for sleep mode, it draws nothing, 0 W.

Also, the cable can withstand high temperatures so it won’t accidentally burn if it touches the soldering iron. That is, the cable doesn’t melt easily, but obviously I haven’t deliberately tested whether it would melt.

Negatives:

1. They don’t give you the 3 tips shown in the photos, but only one. It’s the needle-shaped one, as the stores also state in the description. If you search enough, the lowest price you’ll find for one tip is almost €6.

2. When you clean it on the wire sponge, the tip sometimes gets caught, and if you pull it, it has happened to me that the tip comes out while it’s hot, and you have to wait 1–2 minutes for it to cool down so you can untangle it.

3. The stand has a hole in the center where you put the soldering iron for sleep mode. There’s a round magnet there, like a ring, which puts the soldering iron to sleep. You can also put any magnet on that spot on the soldering iron to stop it heating, but the problem is that it doesn’t stick, so you have to hold it or attach it with tape each time, which obviously isn’t practical. Therefore, I think it should have come with a pen cap containing such a magnet, for people who don’t want to carry the stand around wherever they go to solder something. You can certainly make a DIY cap with a magnet, but it’s a bit difficult.

4. The Type-C connector it has requires 15 volts and obviously doesn’t work at all with 5V Type-C ports. (I’m just mentioning it for those who are wondering, because I had the same question.) If it did work, it would be perfect with a power bank and very practical. But it’s possible to make a DIY power bank that also provides 15V Type-C PD output. And since it draws an average of 6–7 W and has sleep mode at 0 W... it could last for weeks.

5. It doesn’t come with a carrying case, which would be very useful for people who don’t keep it permanently on a workbench. From what I’ve seen, a case costs around €20 (one that fits everything inside, including solder, a power bank, and a cable)... Otherwise, the cardboard box it comes in does the job for putting everything away each time, but it’s not very convenient and doesn’t fit anything else inside.

UPDATE: The soldering iron didn’t work with the only PD 15V power bank (Chinese) I could find and test... but it turned out the power bank was at fault; it wasn’t activating PD, which is why I tried putting a Type-C PD trigger board in between, and the power bank immediately burned out. I don’t know what was at fault... the power bank or the trigger board... it seems like both.

I don’t know what’s going on; it’s hard to find a power bank that supports the soldering iron. However, I tested the soldering iron with a car cigarette-lighter charger that has Type-C 12V PD, and it worked perfectly when plugged in directly. Actually, that’s wrong... it shuts off after a few seconds. So it definitely requires 15V.

UPDATE 25/10/2026: Minus one star because apparently it can’t work with a power bank, etc... I’ve tried EVERYTHING, and when it does work, it takes a very long time to heat up and then gives an error after a while. So if you want a battery-powered one (which makes much more sense), get something else... e.g. the FNIRSI HS-03 Cordless Soldering Iron Type-C, which seems like a much better choice and wasn’t available when I bought the Sunshine.
