Can these lights stay outside in the rain?

They carry an IP64 rating, which means they resist splashes and light rain. Do not leave them submerged or exposed to heavy, driving rain, and keep the USB plug itself dry.

How does the timer work?

The built-in timer switches the strand on and off on a repeating cycle, so you don't have to unplug it each night. Check the strand's instructions for the exact cycle length before relying on it.

Can I plug them into a power bank?

Yes. The USB plug works with a power bank, laptop, wall adapter or any standard USB port, which is handy where no outlet is nearby.

Are they bright enough for a patio?

These are fairy lights, so expect soft accent light rather than area lighting. They work well wrapped around railings, furniture or plants, but they won't light a whole patio on their own.
