iCharge — a powerful modular charging block

iCharge — a powerful modular charging block Why build it?A few years ago, I bought the SW3518 module. It caught my attention as a buck converter supporting a wide range of charging protocols. It was stable, reliable, and most importantly — affordable. Even now, it remains popular, with plenty of positive reviews. I’d recommend it myself — especially the S version rated at 65 watts. If you want more power, go for the P version, which delivers up to 100 watts. But keep in mind: any of these will get hot under full load. That’s why it makes sense to run them at no more than 70% of their rated output — a fair rule for most charging modules with high-frequency MOSFETs inside. Boost Me If you enjoyed my work and would like to support the development of future projects, you can do so through boosts. It helps me move forward, develop new ideas, and share them with you. Every boost is a contribution toward future models that may bring you even more satisfaction. Concept and executionOver time,
