This one.

Scroll down a bit on the page for the promotional offers.

You get THIS and THIS for free with purchase.

Li-PO battery inside gives better longevity. Cheaper than the ankers and bigger. Registering the products at their website gives you 18 months no hassle warranty with a life time warranty. No problems with it so far, have only made 4 full discharge cycles on it. So far, I love them both.


edit:

This is what my checkout screen looked like.

/u/ddow13 down below has some instruction on how it works..pretty simple though

Definitely go with a power pack. I have 88 LEDs on a tophat powered with this guy https://www.amazon.com/gp/product/B00ZZYBAI2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1. Doesn't fall asleep, lasts about 10 hours with FastLED brightness set to ~25/255. Which is actually a little bit too bright for a costume piece that's worn at night. These LEDs pack a punch! Good luck!

It doesn't, I purchased [this battery] (https://www.amazon.com/gp/aw/d/B00ZZYBAI2/ref=ya_aw_od_pi?ie=UTF8&psc=1) and mounted it to my gear vr with velcro tape

Need. So I don't get caught with a dead phone on the side of the road. In the dark. All alone.

Want. So I can send postcards to the wonderful people on r/randomactsofcards. And, well, cats!

A giggle for you.

I'm a professor, so I'm always carrying more than I can fit in my pockets (laptop, notepads, sometimes piles of student papers, etc.). I have a messenger bag that's very simple with not much organization. The main compartment is divided into two parts, one of which has a couple of loops for pens and a small pocket. There's a open pocket on the back of the bag for things that you might want to access quickly. And there are small pouches on the sides of the bag for sunglasses or other small things.

My laptop goes in the part of the main compartment without pen loops. A couple of notepads go in the other part of the main compartment, along with a small case which fits in the small pocket and holds earbuds and a USB drive. Student papers go in that compartment when I need to carry them. My sunglasses go in one of the side pouches (the one I can easily reach while wearing the bag), and a pocket knife goes in the other side pouch (or in my pocket if I'm expecting to use it a lot). The back pocket holds a carrying case with several pens, a small power bank and cables, and a small multi-tool. I also have a small flashlight that can fit in various places depending on how accessible I want it to be, but usually is stored in the carrying case. (I like this carrying case specifically because it lies flatter than most others I've seen, so it's not uncomfortable against my back while in the back pocket of my messenger bag.)

You can also get one of those cell phone charging batteries and charge it while it is in your pocket. I recommend something like

Yeah - very cool idea, though again hard to justify financially next to a battery pack (or a bigger one)

-Bluetooth wireless headphones are always a cool option.
-A really nice leather backpack/work bag.
-Star Wars The Black Series Risk Game.
-This super-cool gaming mouse.


Also, if you have some money left over to spend, here are some smaller gifts that can go in his stocking :)
-A picture of the two of you, in a nice frame.
-Cards Against Humanity.
-These silly floppy disk drink coasters.
-A portable charger. Super useful.

I already put it in the comments, but here here u go..

I have some outstanding chocolate on my list. I only just discovered how delicious Chocolove is!
I have tried the sea salt and almonds, I am curious about the cherries and almond flavor too.

You need chocolate in your carry on bag, and of course reading material. And this for those situations when you need a charge and there is no outlet to be found. This can be a lifesaver while traveling!
