This portable solar battery case charges compatible cylindrical lithium-ion cells and can provide a 5V USB output for low-power or emergency use. It combines a small solar panel, Type-C input, USB output, charge indicator, and removable-cell holder. Batteries are not included.
Listed Electrical Details
- Type-C input: 5V.
- Battery charge output: approximately 4.2V / 1200mA.
- USB output: approximately 5V / 1000mA.
- Red charging indicator and green full-charge indication.
Battery Compatibility
The source lists compatibility with several 3.7V nominal cylindrical lithium-ion sizes, including 18650, 21700, 26650, 18500, 16340, and 14500. Use only compatible rechargeable cells of the same chemistry and suitable condition; do not mix cell types, capacities, ages, or charge levels.
Protection and Package
Listed protections include full-charge stop, overcurrent, reverse-cell, short-circuit, and overcharge protection. Package includes one solar battery case and one power cable. Solar charging rate depends strongly on sunlight and panel orientation, so the Type-C input is the practical primary charging method when reliable charging time is required.
