What to know before buying
Listing details to confirm
The listing gives inconsistent battery details: one field says one included AA battery, while the specification text says 2*1800 mAh rechargeable batteries. It also lists USB connectivity despite describing the lights as non plug-in and solar powered, and lists touch control alongside button controls. Confirm the selected version's battery and controls before buying. The stated operating time is conditional on adequate sunlight, and the instructions say not to immerse the lights in water.
