Look no further! Japan’s Trust Technology’s expanded battery device which is released today, gives your 3DS 5,800mAh. In simpler terms, it gives 4.4 times the system’s standard battery. Your 3DS will become 9mm thicker, but JTT says you’ll get over 10 hours play time.
The battery is available in two sets: with white, red and pink covers for ¥9,980, and with blue and black covers for ¥9,480.
