Power banks across capacities, from slim magnetic packs to high-capacity bricks.
Few realise, myself included, that Panasonic acquired Sanyo about three years ago. On 21st December 2009, Panasonic completed a ¥400 billion, US$4.5 billion, purchase of a 50.2% stake in Sanyo, making it a subsidiary, then bought the remaining shares.
The Sony CP-ELS USB Portable Power Supply launches today at IT Show 2012, Suntec Singapore. It retails for S$29.90 in black or white, with a 2,000mAh capacity and weighing just 87g. My brother notes it can charge a BlackBerry 9900.
I bought the Mophie Juice Pack Boost from the Apple Singapore Online Store for S$69.90, unable to find it at any authorised reseller, which still stock the older 1,500mAh model rather than this 2,000mAh one. It's bigger but far lighter.
My Hong Kong cousin gave me the MiPow Power Tube 6600, which retails for S$125. It packs a 6,600mAh capacity in a durable anodised aluminium case, and bundles charging tips for a wide range of devices.
The Sanyo Eneloop Mobile Booster KBC-L2B upgrades the earlier KBC-L2A, though the model number, merely bumping A to B, is confusing. Sanyo really should pick clearer names so buyers can tell new from old. Design-wise the two are basically identical.
Got the Sanyo Eneloop Mobile Booster KBC-L2S after my old KBC-E1S, running on just two AA batteries, couldn't give my iPhone enough juice. The KBC-L2S lists at S$69.90, but I picked it up for S$57 on eBay.
I found this really cheap external battery charger for the iPhone 3G via HardwareZone forums. The seller, free-4-flying in Hong Kong, runs occasional sales; I've seen it as low as US$6.99, though I paid US$8.48, around S$11.87 including shipping.
Bought the Sanyo Eneloop KBC-E1S for S$34.90 at member price from Challenger, for extra iPhone juice on trips. I weighed it against the KBC-L3S; the E1S uses two AA batteries while the L3S has a built-in lithium-ion cell.
