Recommendations for Powerbanks / External battery backups that can charge the T100

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. .

Great start for a "single subject" thread. I've had one of these for about three weeks and I've been on one of those weeks travelling now.

Considering it carries 20,800mAh of charge, I am impressed with it's recharge rate using my OEM T100 Asus charger. I'm using this battery to charge my T100 as well as my Galaxy S5 as needed and it sure simplified keeping them all charged with minimal cables (1), power brick (1) and (1) portable external battery pack.

When I bought my T100TA it came with a free ADATA PV110 rated at 10400mAh

While it seems to work alright for charging off the 2.1A port I can't seem to get it to pull more than ~2600mW for a charge rate at idle, less if I'm using it heavily. Of course that all makes sense. I also have a monoprice 9000mAh pack with 2.1A output as well.
External Battery Pack and Charger for iPad®, iPhone®, iPod®, and other USB Mobile Devices (9000mAh) - Monoprice.com
A steal at that price, I bought one two years ago at $50, and another about 6 months ago for $40, the build quality is fantastic and after 2 years of being abused (and then pulled apart and connected to a solar panel and charge controller from Adafruit for even more abuse) it still holds at least 7500mA accounting for voltage conversion from battery to USB voltage. It usually pulls around 3600mW for a charge rate at idle, definitely more punch than the ADATA. I would like to note that both of these (using a charge only cable in all cases due to the Dell being a whiner) packs will peak out just beyond 5500mW for an idle charge rate charging a Dell Venue 8 Pro with a 3740D Atom. I know the smaller screen and lower clock come into play here but to compensate the Dell is at full brightness and the T100TA at lowest. The dock on my T100TA has the HDD dismounted and unpowered most of the time, however undocked results in no change of charge rate. It's a little disappointing that the ADATA doesn't quite match the Monoprice pack with the T100TA but is completely comparable when charging the Venue 8 Pro.

Plugged in with the OEM charger the T100TA pulls between 6000 and 6500mW as a charge rate, using the Dell OEM charger it is between 1500 and 1900mW at idle.
The T100TA OEM charger will not charge the Dell due to the lack of bridged ground, but the OEM Dell charger does a rate of about 3600mW at idle for the Venue 8 Pro.

Just some numbers in my experience to compare with mostly :)

I use Xiaomi Mi Powerbank 10400mAh and it's great, but charger only with it's original cable which is like 15-20cm long...

I know this thread is a bit old, but which solar energy-based Power Bank you guys recommend for me? Highest mAh if possible.

I haven't spent any time reading the thread however pretty much every power bank is the same with a slightly different casing.

Their are however some that deliver 2.1 amps as opposed to the standard 1A in cheaper models. Something to look for since you want to be able to charge while using the tablet.

I've never seen a spec for the mAh capacity if the t100, I would expect on the order of 10000 mAh so choose accordingly.

If anyone does electronics here you can confirm this, I think im right. If you connect the positives together and the negatives together of two power sources. Such that both power sources are IN PARALLEL, the capacity in total is supposed to double.
In other words doing this doubles your mah. Doubles the current you can use for a continous hour. but the VOLTAGE stays the SAME.

Am I correct in saying this should add up the max current from two usb ports aswell.
Im planning to get this Swees® 25600mAh 3-Smart-USB Power Bank Portable: Amazon.co.uk: Electronics
and then two usb to micro usb cables with it, tear one of the two usb cables open and connect the positive cable from the usb end to the positive of the unbroken usb cable, same with the negative. This connects it in parallel?

Im then gunna tape it to the back of the tablet and add a switch to the usb cable

The official product page lists it as a 2Cells 31 Whrs Polymer Battery. By using Whrs you account for the change in battery voltage

E(Wh) = Q(mAh) × V(V) / 1000

For a 10,000 mAh battery bank contains 10,000 x 5/1000 = 50Whrs

Late entry to the party: 2 questions:

Question 1
Bought an Aukey 20,000 mAH charger for $38 CAD. Thought I would need the capacity but now I realize that the tablet's capacity is 8,000 mAh, not 27000mAh (I now realize BatteryInfoBar reports in mWh...oops!). Anyways it's a bit much for me (this thing's beastly heavy).

The issue is that in a high draw situation (game running, speakers on 20%, max screen brightness, wifi on) the battery pack can't keep up.
Is it bad for the battery to lose power as it charges? I did that to my phone ones and I can't tell if it's my mind or not but it seemed worse....

Question 2
For those with the Anker 2nd gen: can it keep up with the tablet under a high demand situation?

To answer your first question. I can't say for sure but the standard output if most higher end external batteries is 2.1A. Your original charger is also 2.1A. There isn't any problem using more power than the charger or battery can supply on its own it just means you still get a net battery drain while putting such a high power load on your machine.

If the 2nd Gen model can output at 3A AND IF the t100 can support a 3A charge (otherwise it only draws the max 2.1A from the battery) then you would see some improvement. Can't say for sure if you can charge at 3A though.
