I had the same question and posted in the youtube comments. 
Since noone answered, I did some searching.
Here are the two battery backs that he uses:
Chargetech portable power outlet
RAVPower Xtreme 23000mAh Power Bank
 
Hope that helps. I was hoping the Ravpower bank was a bit bigger, say 40 or 50 Ah. I might've bought it then. 

Can I just point out that according to Linus 75 fps max settings on a 980 in Battlefront isn't a bottleneck but then you have a 970 getting 100 fps and a 390 getting 112 fps. Yeaaaaaaaaaaah

Watch his R7 240 review. It's a load of bullshit.

I'm unhappy to see the way linus YouTube has evolved. I'm very disappointed and regardless of "current" market share. Equal discovery on amd cards is warranted. Providing incomplete data is not fair to the consumer or are you not consumer friendly anymore. The whole point behind your channel was to help techies or has that changed as well.    
 
thx to linus, I have downvote my first video on youtube

Disappointing and even unprofessional video, especially for someone of your magnitude, guys.
 
1. The card you used is way too old, something more relevant like the gtx780 or 780ti would be better. I mean who cares how optimized your drivers would be after 5 years(seriously, 5 fucking years?), drivers are optimized withing weeks/month not years and when people say mature they usually mean that period of few weeks/month. Test of drivers up to 2 year after a card is released is more than enough, hence why you should used a newer card(and would allowed you to use AMD card if that's your excuse, *point 3 below). 
 
2. One month after a card is released drivers are already too old. As I said drivers are optimized withing weeks if not days after/during release so what you ended up testing(by starting with  1 month old drivers) is a bunch of already optimized drivers. You should have started with the first released drivers that adds support for the card you're testing(even if the driver come out before the card was released for sale).
 
3.  No AMD? I don't care how much % of people use AMD/Nvidia. AMD cards have enough people using them that they deserve testing just as much as Nvidia cards. If you really care about percentage and appealing to the "majority" of your userbase you should've made a strawpoll and ask you audience to vote(just because statistics or whenever you pulled that 80% from show that 80% of the general users use Nvidia, doesn't that it's the same percentage for your specific type of users that watch you). Also why cover only "80%" of users when you could easily covered all of them(use newer nvidia cards, or if you really don't want to then use old nvidia and newer amd cards, there is no excuse not to use amd considering your fanbase and the hardware resources your company has).
 
4. Put you tinfoil hats gentlemen. Now something else that would have been interesting to see is: does Nvidia/AMD cripple their drivers when a newer generation of cards is released, for example are 780/ti drivers crippled after 970/980/ti were released or the same with radeon 280/290/x and 390/Fury/whatever.
 
Now, with all that it would've been an interesting, objective video looking critically at all aspects of your topic(Then vs Now Video Card Drivers).
Sorry guys, but the weird way you did the tests and the video, it looks as if Nvidia threw  a bunch of cash at you and told you to make an ad for them(I know it sounds ridiculous and blaming but that's how it looks).
 
EDIT because replies:
My comment is targeted at Linus and the guys involved in this video and I don't really care that much about the opinion of my post by the other dudes here. I'm not big on posting in forums anyway. Although my initial post is negative, it's meant as a critique not hating so If anyone from LMG is reading it(I hope so, otherwise it's pointless), don't take it the wrong way. I've been a subscriber of LTT for awhile(and the other channels since they started), love the LMG team and what they do, except for that particular video which is the first LTT video I pressed dislike on and disagreed with to the point of going to the forum here and giving my 2 cents.

I heavily doubt that 80% of your audience own an Nvidia card. While it is probable that Nvidia card owners are more abundant over here, it wouldn't stretch to 80%. This is because people in this community are mostly PC Builders which make educated decisions with regards to purchasing their parts. Nvidia's 80% market share is aided by the fact that most prebuilt Dells and HPs have Nvidia GPUs preinstalled (GT 610 and GT 730 for example), and even within PC builders some buy parts without realizing their comparative performance and the general consensus in the public is that Nvidia GPUs are better across the board, so people seem to go with that. Over here I would guess the percentage is more in the 60-40 range though.
 
Not claiming any bias, just stressing the importance of making similar comparisons for AMD cards as well.

What about Amd cards? 
 
Also: Are you jumping the vessel ship? What's today's vessel video? This video is both on YouTube and Vessel. 

I wouldn't have agreed until the recent string of fucked drives I got from NVIDIA from the release of witcher 3 until recently. Least I wasn't a 980ti owner, I could actually use old drivers that worked. 
I've always thought AMD's drivers were worse, but better in principal. Better gpu support, didn't wait several years to support basic begged for features like hdmi full color range (and patch it out when people forced it in), ect

My point was more to see which company actually has better driver support in terms of performance, because the amount of people saying, oh well Nvidia/AMD has so much better driver support than Nvidia/AMD. Shame you don't have an old AMD card though.

@LinusTech What about AMD's cards?

The video is on Vessel and Youtube.

Now do this with AMD for a truly interesting comparison; although that probably won't happen because we all know that Linus has been getting sponsored more by Nvidia Linus is biased towards Nvidia. Really annoying actually. @nicklmg

I've been mentioning this for months. You would think a "new video email" implementation isn't hard to come up with. LMG caters heavily to the youtube audience and Vessel seems like an afterthought at this point. (And it probably still will be an afterthought until March 2016 when "Vessel viewer retention" strategies are finally in place.)

Can you link to the exact one Linus used?

Sweet, and best of all nobody took my user name

Update, looks like this one: http://www.amazon.com/dp/B00R14XSUW/
