Frequently Asked Questions
All your fairy lights questions — answered.
What batteries do Jcfyoo fairy lights require?
Battery versions require 3×AA batteries (not included). Standard alkaline AA batteries provide approximately 6–8 hours of runtime on steady mode. For unlimited runtime, choose a USB variant — plug into any phone charger or power bank.
Are Jcfyoo fairy lights safe for kids' rooms and nurseries?
Yes. All Jcfyoo battery string lights run at 4.5V DC low voltage — LEDs and copper wire stay completely cool to the touch during normal use, making them safe for kids' rooms, nurseries, and contact with bedding and curtains.
Do you offer free shipping?
Yes — all orders over $50 ship free worldwide with full tracking. Orders under $50 have a flat international shipping fee. Every order includes a tracking number sent by email.
What is your return policy?
We offer a 30-Day Money Back Guarantee. Return unused items in original packaging within 30 days of delivery for a full refund. Contact support@jcfyoo.com to start a return.
What is the difference between battery and USB fairy lights?
Battery fairy lights (3×AA) are fully wireless — place them anywhere with no cord. USB fairy lights plug into any phone charger, laptop, or power bank for unlimited runtime without replacing batteries. Both options feature the same cute themed ornaments and warm white glow.
Do the ornaments look cute when the lights are off?
Yes — the themed ornaments (animals, florals, ocean creatures, holiday designs) look adorable in daylight and create a warm cozy glow at night. They double as room decor even when unplugged.
