Then I went to ebay to find a 50,000mAh for only $23!!!
Except it has no brand name on it...

Which one is better quality?
What do I buy?

P.S. This power bank will also charge my phone and other various items.

I recently bought a 10000mAh power bank for 11€ in amazon, and it works really well, the advertised capacity is true. The 50000mAh one on ebay surely it has much lower capacity than advertised

It's got to be fake

The 50,000 mAh one sounds suspicious. It's probably only got one 2,000 mAh lithium cell and the rest of the internal space filled with bags of sand. I've seen ones claiming to hold 100,000 mAh go for £12 before (funnily enough while the listing claimed 100,000 mAh, the images advertised only 13,000 mAh).

Ok should I buy one with a brand/company name on it?

Yes, definitely go for one from a trusted brand. Even if a non-brand model has the advertised capacity, there's no guarantee it will be safe to use.
The 3DS is rated at a charging current of 900mA, so anything that supplies 1A or above will do. If you want to also charge your phone, 2A should be your target.

I will buy a Cygnett InCharge powerbank that's 5000mAh.
It's buy one get one free so the total will be 10000mAh!

Btw are power banks like micro sd cards where it's not exact.
For example, my 32gig micro sd card has only got 29.7gig available.

Btw my power brick supplies 5V to 1.55 amps and this powebank is "Features 1 Amp / 5V".
Is that ok?
I've heard that using other chargers voids the warranty is this true? Does it apply to powerbanks?

5V/1A should be fine, it should not void your warranty.
Power banks may have some slight inconsistencies in capacity, but this is normal.

So will that mean it charges slower

Actually, the rated capacity on flash storage is accurate, technically it's OSes that's not using the SI prefixes correctly, but it's become such an accepted use of SI prefixes that people expect 1 KB to be 1024 bytes and so on, when 1 kilo = 1000.
Kibibyte (KiB) etc. were created as a new term to mean 1024 to clear up that confusion but it hasn't really caught on.

Powerbanks will never measure at the exact capacity they're rated for, as it's not an exact science. With 3rd party and noname brand batteries the capacity can vary wildly, but with 1st party batteries and known good brands it should be around the rated capacity, maybe even a little higher.
