Panasonic – USB Portable Power 10,260mAh (QE-QL301)
In my post on the Panasonic Mobile Booster QE-QL101, I mentioned Panasonic's larger 10,260mAh portable battery, which I couldn't find in Singapore. I eventually spotted it in Thailand and bought it for TH฿3,990, about S$160, dropping to roughly S$150.
