I’ve got a Hakko FX-901 Cordless Soldering Iron and I love it. I was reminded how much I love it when Donald mentioned it in Maker Update #37.
I got mine about two years ago after using one at the Be A Maker space. I stick a set of rechargeable AA batteries in it and I’ve usually got it ready to go when needed. Oh, while you can find it on Amazon for about $32, I got mine from SparkFun where it’s usually $34.95 but you can sometimes find it on sale for $24.95, which is an awesome deal!
The one thing I don’t like about it is the replacement tips. Right now a Hakko T11-B Tip for FX-901 is $24.95. Yeah, that’s the same cost as a new (on sale) iron from SparkFun. Hmmm…
I know some people really like the butane soldering irons, and they can be found for cheap, but I prefer rechargeable batteries to dealing with butane fuel. Also, I’ve flown more than once with the Hakko, and bringing AA batteries on a plane is not an issue. :)
