Pros & Cons
Hakko FX-901/P Cordless Battery Soldering Iron
Pros
- Genuinely cordless — battery-powered, no bench outlet or station box required
- Useful as a field or automotive second iron when a mains station isn't practical
- Hakko's reliability reputation carries over from the FX-888D line
- Inexpensive enough to keep as a dedicated travel iron alongside a bench station
Cons
- 6W output only handles light-gauge wire and small joints — not a PCB rework tool
- No digital display, temperature lock, or adjustable set-point — a simple on/off battery iron
- Heat-up time and battery life are both noticeably worse than a mains station
- This is a second iron, not a primary bench tool — pair it with a real station like the FX-888D
Weller Brass Sponge Tip Cleaner with Silicone Holder
Pros
- Brass sponge cleans tips without the thermal shock of a wet cellulose sponge — extends tip life
- Silicone holder base is heat-resistant and won't scorch the bench like a bare metal tray
- Works with any iron in this roundup, not just Weller stations — a universal accessory
- Genuinely under-$10 upgrade over the wet sponge most stations ship with
Cons
- Brass wool needs periodic replacement/topping-off as it packs down with use
- Doesn't remove heavy oxidation the way a tip-tinning compound does — it's maintenance, not restoration
- Marketed as a Weller accessory but is functionally identical to generic brass-sponge cleaners — no real brand premium beyond the holder
