Get the XIAOMI Power bank+the pistons at 32$.
I received it 2 weeks ago, and still deciding if powerbank is legit
All technical things tells it's OK, short circuit(out&in short circuited) is ok it's not charging itself, pass-trough is working (charging while being charged), button press&hold while bank is being charged also works as charging stops and continues after button is released.
Few things got me to opening it up, font color on the bottom(where 10400 is written) is slightly different that older bank I have(which have LG batteries inside), though quality of font is still good, just the color, its clear not blurry and it's light not dark, but somehow blueish. Also, on bottom it says mi.com, not xiaomi.com like on older bank I have. Also in papers it says http://fuwu.mi.com So I decided to open it
Inside, pcb board looks same like xiaomi said. Quality and finish of aluminium case is also good. Connections between batteries are also good, it also have thermal sensor. LEDs are slightly stronger but still they have shading paper. Only thing that's bugging me is battery color. They are green.
I have been using this bank for this 2 weeks and it's working like old one, charging times, approx. capacity..all looks fine, except those green batteries(lr1865sk).. Ok, micro usb port on cable also have lightning mark, but looks like it's ok, cable that came with older bank had dash in same place.
If this is fake, than it's damn good fake
Even the code on box says it's legit and that it's checked only once(by me).
Looks like I should contact xiaomi and ask them
