شحن LiPo مع وحدة محول رفع جهد Boost

Took a chance on this for a DIY project and it’s been solid—the 1A step-up output actually holds steady under load, which surprised me. Charges my cell cleanly and the boost side runs my little fan without drama.

I needed something compact to charge a 3.7V cell and boost it to 5V for a portable project, and this board does both without a hiccup. The 1A boost output is enough for my small LED strip, and it’s held up through several charge cycles.

Finally a tiny board that charges my cell and boosts to 5V in one go, no extra wiring. The 1A output drives my little fan without sagging, and the charge LED is bright enough to see across the bench.
