okay, like me, you'll probably receive this and it looks very shiny and like the much more expensive ones from the main brands. but one to two months after having this, I'm starting to realize it wasn't designed super well.. (whether it's the foldable aspect of this, or just overall design) the block does not stay in many outlets. I use it at the gym, where the electrical outlet is really loose (my other bricks work! this one will be too heavy and fall out). Then I also use it at home, where the plug and plate are really flush and nice (and this will still be too heavy and "unsync" from charging).
Sometimes I only can plug this thing in "upside down", and on the top of two wall plugs (with another plug or brick plugged into the bottom outlet) so that the heavy weight of this brick is propped up.
it really likes to sit at a flush 90° angle in the wall, so often times when it's like at 85° or 95°, it won't charge!!!
this messed me up a couple times because I plugged it in and left for hours thinking this was going to do its job, only to come back and realize it hadn't been charging after the 3rd or 4th second it was plugged in!!!
save yourself the money on this one and get another one, or just go for a GaN charger brick from one of the reliable brands.
