✦ Frequently Asked Questions — USB String Lights
Why choose USB string lights over battery string lights?
USB string lights are the better choice when you need unlimited runtime, have a USB power source nearby, or are using higher LED count designs (100+ LEDs) where battery power drains quickly. They’re ideal for permanent desk setups, shelf displays, and any space where you want continuous glow without replacing batteries.
What can I plug Jcfyoo USB string lights into?
Any standard 5V USB power source works — phone chargers, laptop USB ports, power banks, USB hubs, and smart plugs. No special adapter required. If your device has a USB-A port, it’s compatible.
Are USB fairy lights safe to leave on for long periods?
Yes. Jcfyoo USB string lights run at 5V DC low voltage — LEDs and copper wire stay completely cool to the touch during normal use. They are safe for extended display use. We recommend using a timer plug or smart plug for overnight use.
