Portable mobile boosters and battery packs.
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 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.
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.
