What to know before buying

Listing details to confirm

Listing details are inconsistent about control: the specifications list a remote, while the feature description says to change modes using the button on the transformer. The listing gives 110 volts for the outlet and 29V output, while another field lists 18 watts and DC. Confirm the included control and electrical details before purchase. The waterproof claim is accompanied by IP44, so do not treat it as a claim of submersion protection.
