While the module supports charging the battery while a load is connected to OUT+ and OUT- , it is not highly recommended. The load can trick the TP4056 into thinking the battery is still absorbing current, preventing the chip from properly terminating the charge cycle.

The HW-044 is a highly popular, low-cost lithium-ion battery charging module built around the TP4056 linear charging IC. It provides a simple and efficient way to charge single-cell 3.7V lithium batteries (such as 18650 cells) using a standard 5V USB input.

If you are charging smaller batteries (e.g., a 500mAh LiPo cell), a 1A charge rate is too high and unsafe. The ideal charge rate for longevity is 0.5C0.5 cap C
