Bought the Sanyo Eneloop Mobile Booster KBC-E1S for SGD$34.90 (member price) from Challenger. Need the extra battery juice for my iPhone 3GS when I am in Taiwan and Hong Kong!

I was deciding between the KBC-E1S and the KBC-L3S. The KBC-E1S uses 2x AA batteries while the KBC-L3S uses the built-in lithium-ion battery. I was thinking that AA batteries are more readily available outside and hence I am able to buy any AA batteries and use it to charge my phone. Also the KBC-E1S includes 2 rechargeable eneloop batteries.

*Update* My iPhone 3GS is on 25% battery and I started charging at 00:00 (midnight) exactly. The Mobile Booster KBC-E1S was drained completely at 1.20am and my iPhone 3GS was charged till 71%. So that makes it 80 minutes to charge 46%.

    Does it actually show up as ‘charging’ when plugged into the iPhone? Got any specific run time data to share yet?

    I am testing it now, shall share it once the test is done =D

    Edit: Done, I have updated the post

    50% charge for iPhone is too little. Do they have another version that uses 4 AA battery? If yes, I think it would be better. :)

    I don’t think they got 4 AA, the rest are all built-in li-ion battery. I tested the second time, this time it took 100 minutes to charge 48% so the results is about the same. I think maybe li-ion maybe better.

    After reading wiki,

    “The capacity of rechargeable AA batteries varies with the technology used. Nickel-cadmium (NiCd or NiCad) AAs with a capacity of 500 to 1100 mAh are available, cost increasing with capacity. Nickel-metal hydride (NiMH) AAs are also available in various capacities ranging from 1300 to 2900 mAh.”

    “Primary (non-rechargeable) zinc-carbon AA batteries of 400–900 milliamp-hours capacity are commonly made using Leclanché cell technology. Zinc-chloride batteries of 1000 to 1500 mAh are often sold as “long life” or “heavy duty”. Alkaline batteries from 1700 mAh to almost 3000 mAh cost a little more, but last proportionally longer.”

    It seems like if I use Alkaline will have a greater charge, shall test it tonight.
