I can confirm both my Jackery power bars work on the T100.
I own the 6000Mah orange one and the 12000Mah jackery giant. Both are exceptionally great quality. Tried tested and true. They have handy emergency flashlight as well(actually comes in really handy when power goes out. 6000Mah one lasts 490 hours. lol). They hold a full charge for up to 6 months. charge the tablet pretty fast for the most part in sleep mode.
Picked em up for travelling, camping and power failures. One for phone, one for tablet. I have owned a few different brands and really love Jackery for its superior quality. These things take a beating. I literally have beat the snot out of em and dropped them countless times. They are by far the sturdiest power bar i ever owned.
~Jackery giant 12000Mah comes with 2 ports . One 5v, 1 amp for phones and a 5 volt 2.1 amp for bigger stuff. This one charges my tablet completely from dead to full with enough juice for a phone charge or two left over..Usually goes on sale on amazon for like 39.99-49.99 bucks. Regularly 129.99 http://www.amazon.com/Jackery%C2%AE-...dp/B00AANQLRI/
~Jackery bar 6000Mah comes with only one port that is 5v, 2.1 amp. This charges my tablet from around 20% to full give or take a few % and has no charge left when its done.. Usually goes on sale for around 24.99-29.99. Regularly 89.99 http://www.amazon.com/Jackery%C2%AE-...dp/B00AANMVNQ/
So if you can wait for sale i would say its worth it. if you cannot find deal then maybe go with cheaper one. I can however confirm they both work great and have saved me countless times travelling and sitting in dark during power outages. .
