Set up your charger.
Follow the instructions to finish setting up your charger. After a minute, it should appear on the map. Until your Splash QR sticker is on the charger, guests can't actually use it — that's how they start a session. Send us a screenshot of your charger on the map via the "Need help?" link below, and we'll get a sticker in the post to you.
