Frequently Asked Questions

Q: Do I need to buy 18650 batteries separately for this power bank case?

A: Yes. The Gaqqee 8×18650 power bank casing is sold as a casing kit only — batteries are not included. You will need 8 × flat-top 18650 cells without a built-in protection circuit. Make sure all cells are in good condition before installing them.

Q: Which devices is the PD 65W model compatible with?

A: The PD 65W model supports a very wide range of devices including smartphones, tablets, and laptops. Its USB-C output delivers up to 65W via PD 3.1, and its adjustable DC output (3.3–24V) makes it compatible with most DC-powered electronics. Most mobile phones are limited to 33W by the manufacturer, regardless of the charger used.

Q: Is any soldering required to assemble this power bank kit?

A: No soldering is needed at all. The solder-free snap-in design makes assembly straightforward, even for beginners. Simply insert your eight flat-top 18650 cells, close the casing, and charge to activate.

Q: What does the LED outdoor light function do?

A: The built-in LED provides hands-free illumination for outdoor activities, camping, or emergencies. On the 22.5W model, long-pressing the button activates the LED and enables low-current mode simultaneously; a single press then cycles through lighting modes. On the 65W model, double-pressing the power button enters or exits LED mode.

Q: Is this product safety certified?

A: Yes. The Gaqqee power bank casing holds CE and RoHS certifications, meeting international electrical safety and environmental standards. It also features multi-level built-in protection circuitry to safeguard both the casing and connected devices during operation.
