Caveats
- The cooling fan runs while charging and owners describe it as loud.
- No waterproof rating is stated; use Redodo's IP65 10 A model for a wet boat locker.
- Redodo's page does not list the included output connector; check it against your battery terminals before buying.
- Charges LiFePO4 only; it has no lead-acid mode.
