I can use the same wall plug or portable battery for my laptop, phone, and soldering iron, and it has a bunch of nice qol features.
There's an accelerometer built-in so it can detect when you put down/pick up the iron for sleeping the heater and also for orienting the display. The new version also has Bluetooth so you can monitor/control the iron from your phone/PC.
The heating element is in the tip so you are less likely to burn your fingers and it's also far more efficient so it's able to heat up very quickly and handle large pads for its size.
It can draw up to 85W through a barrel jack or USB-PD.
I paid $25 for it and have gotten a ton of use out of it.
I put away my expensive soldering iron and use this one exclusively now because it's just more convenient to use.
I would definitely recommend it for new or experienced users, it's a great value for the price.
Doesn't help that the official one is on aliexpress with a bunch of knock offs. But the actual pinecil works really well with the same 60w charger I use with my pixel 4a.
