I now have 4 of these, one of which I think has died. For cycling, they are very handy. I use recycled laptop batteries and get very good performance. Because bicycles are mostly round tubing and this thing has flat sides, I 3D-printed a part that I glued to the battery case and which snaps around the top tube on my mountain bike. It keeps everything neatly in place. See attached pictures.
Great universal power bank. Batteries is connected 2SP (two serial and these serial groups parallel). Is usable as USB power bank!
muito bom
Dobrze wykonany materiały dobrej jakości. Działa tak jak należy :)
W sam raz na rower do zasilania oświetlenia a także umożliwia ładowanie urządzeń poprzez port usb w tym samym czasie. Polecam.
