Thank you for posting and welcome to the community.
We're sorry to hear you're having trouble with charging your SoundLink Revolve.
The SoundLink Revolve is designed to be water resistant, and withstand splashes of water, not fully water proof. As your speaker appears to have encountered excess water, I would advise you let the speaker fully dry out for at least 48 hours before further use.
If you still have trouble charging after this time, let us know and we'll be happy to help you get it back up and running.
