Promaster Traveler Flex 充電器，適用於可換鏡頭相機電池

This thing charges two batteries at once without any fuss, which is exactly what I needed for long shooting days. The compact folding plug makes it easy to toss in my bag without worrying about bent prongs.

Picked one up for my mirrorless kit and the USB-C input is a lifesaver—I can finally charge batteries from my laptop on a plane without hauling a bulky wall brick. It's compact enough to slide into a side pocket, and the sliding tray adjusts to fit different battery shapes.

The fold-flat design is genius for travel, and it charged both my batteries without any overheating. Took up barely any room in my backpack, which is exactly what I needed for a week of shooting.
