Great product. Great communication.


All that and a bag of chips

This product is solid the battery life is great. I no longer feel tied to a power outlet and I don't have to worry about leaving the unit open.

The battery cover is solid and very comfortable for larger hands. The plastic does not feel flimsy and it attaches to the unit snugly.

If your worried about weight it's there but hardly worth the mention. Use 2 hands and you will not notice. The battery life is the real star here a bit high for a battery and cover but honestly I would buy it again.

I really like this battery the life on it is Incrediable, thanks for creating this awsome product. =)


Great for big hands and long sessions

18 April 2014


The size of the mugen battery pack actually makes my 3DS LL fit easier into my hands, it has a fuller feel. There is some additional weight. If this bothers you go work out your arms, because it's still light and shouldn't hinder anything. I like the weight now; it feels like I'm holding something important.

Some gripes I had on delivery/install:
The box it was delivered in was fairly caved in at one side (this was to Japan). There was a small scratch on the battery cover.

What really bugged me though was that the mini screwdriver that came with the pack was not able to unscrew one of the two screws holding my original battery cover in place. So in the end I had to tear the cover off after destroying the screw (trying to get it out). So my original cover is ruined.

However, all that aside: Will I ever need my original cover again? Probably not. Will that scratch really bother me? Probably not.
Do I love my new battery pack? Absolutely!

I can play for at least two long whole days (I had some time off) and it still isn't drained. Especially recommend it if you have big hands, because it feels better than without in my opinion.


Exactly what I needed.

1 April 2014


I'm a frequent traveler, and will sometimes spend several days traveling with only limited access to power sources. While I /do/ carry an external battery pack for some of my mobile devices, having a built-in high-capacity battery is exactly what my 3DS XL needed. This battery lasts for /ages/. I say this anecdotally, as I haven't actually performed any timed tests on the battery, but I have noticed a perceivably enormous leap in battery lifetime using the mugen battery.

The replacement back-plate that shipped with the unit was also in great condition, and feels like a natural fit.

If or when this battery wears out, I'll definitely buy another.


Beyond Expectations

25 February 2014


I got my Mugen battery for a 5 day camping trip. I had played on my 3DS XL at least 3 hours each day I was camping and I had only used barely half of the battery life. That is 15 hours of gameplay. If you plan on using your 3DS XL extensively, the Mugen battery is a must have.


Exceeds Expectations

23 February 2014


This battery can last more than a month in sleep mode. Nonstop gameplay will last 10 hours.

Good battery life, cant say its not a good buy, but they did not give me the right size for taking the case off. Had to buy my own set just to get the case off, but really good battery. Using it by day, charging it by night.
