The comparison is always against http://www2.fsplifestyle.com/home/pr...Key=P161000029, the Zolt is 93mm * 34 * 34 , the Twinkle is 71 x 49 x 24mm -- so the Zolt is bigger but in one dimension, however, if you add the Aukey 12W super small USB charger then the space used roughly evens out and you need one less power port which is always handy. I might try the Zolt... thanks for pointing out it is now available.
