There are tons of MagSafe battery variations, and I may own most of them. The new TESSAN AERO 5000 caught my eye because it’s really thin and has a titanium finish. It also uses a new battery technology to reduce heat and improve overall safety. After reviewing the entire spec sheet, I think this might be one of the more interesting MagSafe batteries hitting the market this year, and I can’t wait to get my hands on one.
