I have had the Twinkle 65 for almost two years although my daily usage has now been reduced to semi-weekly since I got a hybrid tablet/laptop that can be charged via USB. The power cord is longer but very thin, which reduces weight but also leads to that "kinky" feeling you get with some electrical cords that makes you think it's not going to last. I haven't had that issue nor have I seen this reported by other users.

It's half the cost of the Zolt on Amazon and has worked well for me with HP, Toshiba, Samsung, and Lenovo laptops, but I've read consumer reviews stating that it doesn't play nice with Dell computers (reports of "plugged in, not charging" from the battery charging icon in the taskbar). Although I can recommend the Twinkle for most uses and actually like using a separate Anker charger because I prefer a setup that allows my phones to be plugged in and placed on a nightstand or desk rather than on the floor near an electrical outlet (not an issue in many hotels where outlets are placed on or around a desk), I think you're better off with the Zolt.
