Running Out of Battery in the Middle of Nowhere Is More Than an Inconvenience — It’s a Safety Risk
Whether you’re camping deep in the countryside, hiking a remote trail, or dealing with a power cut at home, a dead phone or device can leave you completely cut off. Standard power banks are convenient until they run out too — and then you’re stuck waiting for a mains socket that might be miles away. What you need is a power solution that can recharge itself from the sun.
This 18650 Solar Power Bank Charger DIY Box lets you build your own high-capacity portable battery pack using five 18650 cells (not included), with a built-in solar charging panel that keeps it topped up wherever there’s daylight. With a 10,000mAh capacity when fully loaded, it’s enough to charge a smartphone multiple times over — completely off-grid.
Solar Charging That Actually Works
The integrated solar panel provides a genuine renewable charging input — ideal for extended outdoor trips where mains power isn’t available. Position the case in direct sunlight and it will slowly replenish the battery cells throughout the day, giving you a self-sustaining power source for as long as the sun is shining. Combined with the standard 5V 1A USB input, you can also top it up conventionally whenever you have access to a socket.
Dual USB Output for Multiple Devices
Two USB output ports let you charge two devices simultaneously — phone and tablet, phone and headphones, or any combination of USB-powered devices. Output 1 delivers 5V 1A for standard charging; Output 2 delivers 5V 2.1A for faster charging of compatible devices. The LED indicator shows remaining charge at a glance.
DIY Flexibility — Use Your Own 18650 Cells
The case accepts five 18650 lithium cells, giving you full control over the quality and capacity of your power bank. Use high-quality cells for maximum performance, or repurpose cells from old laptop batteries for a sustainable, cost-effective build. The compact 12 × 7.5 × 2cm form factor fits easily in a backpack pocket.
