10 days on Blue Manta in October but need to charge and recharge. They have European connections but alas I, and my equipment, are American. Can I take one power converter and attach it to a power strip? I will have 2 dive camera batteries, 4 video light batteries, 2 chargers for strobe lights, 2 kindles, one computer. Don't want to blow anything up but also don't want 8 power converters.
