Three xCool Boxes: An Adapter Cable, USB-C Batteries and a Magnetic Power Bank
Opening the accessories and getting a charging indication on my phone.
Article published November 4, 2026.
This is a proper little loot drop: three xCool/Cool Gadget packages, with different charging ideas in each. I take them one at a time instead of going straight for the largest box.
The cable has adapters at both ends
The first package is a green cable with USB-A/USB-C at one end and Lightning/USB-C options at the other. I open and close those connectors, then find a roll of cable-management material and a desk fastener.
I discuss the labeled power rating, but do not measure it or test every connector combination.
The batteries have their own USB-C ports
The second box has rechargeable AA-shaped cells and a multi-ended charging lead. I show the ports on the cells and fit the charging connectors.
This is not a capacity, endurance or device-compatibility test, and I do not establish that these cells can replace every other AA battery type.
The power bank reaches the phone
The last package has a thin magnetic bank, a stand accessory, cable and attachment piece. I put the bank on my phone and it shows charging. That is the actual powered result, without measuring charging speed or a complete battery cycle.
xCool sent these for the video. Their precision screwdriver set is another session where the included accessories caught my attention, with a very different job to do.
