Need your help to test mobile booster on the phones available on the market.
Mobile booster will be provided.



We have very limited resources of Sanyo Eneloop mobile booster on the internet. We don't know if our devices is supported, and we don't know how many times it can fully charge our devices.

And this is why I started this thread. Let's us share our experience.

Just back from KL+SG trip.

1. There 2 kind of AA charger, One take 110V/230V AC adapter as power input, and another take USB as power input.
The USB AA Batteries Charger is MDU01, and it's not available here. more info here:
http://www.eneloop.info/products/chargers.html


2. KBC-E1S Mobile Booster uses 2 AA batteries. It can function as a AA battery USB charger, as well as mobile booster to charge your devices.


3.KBC-E1S is not available, you have to search for ex-stock on the market. I'm waiting for the Eneloop Stick mobile booster to arrive in November, it's similar to KBC-E1S, but in the form of stick.

1.No, There's no such commercialized solution. Even tho it's possible, but it's not practical.
(on some buses, They have a 12V DC--> 110/230V AC converter to power the TV. I don't think it's portable, but it's fine to charge at home)

2.USB only supply Maximum 5V 500mA, and it's slower than the AC charger.


------------------------------------------------------------------------------------
Btw, some out of topic info sharing:

Higher the numbers (Voltage, Current...), could potentially damage or shorten the life of battery.
Try google "charging algorithm", A good charger fully charge your battery faster without damaging your battery.

So, beware of the china made "super fast charger". It may be faster, but you wouldn't know if it's using the right charging algorithm, or they don't even have charing algorithm.

I agree with you. KBC-L2AS-SP is using Li-ion battery, the same battery type on handphone and laptop battery.

I think it should last 1 year+ as well, and battery capacity will drop afterward.

(**KBC-E1S is using Ni-Mh AA battery, i assume the life span is much shorter. But you can always replace a pair of new AA batteries)

When your phone battery is low (say 15%), it charge up to 50-70% very fast.

Doing the testing now, I'll post the result later.

Have to wait until November only can get stick booster. I've seen some seller selling the stick booster on ebay tho.

I charged my Samsung Galaxy S this morning, here's the result:

32% 8:47AM
43% 9:10AM
46% 9:20AM
51% 9:33AM
58% 9:49AM
65% 10:04AM
68% 10:10AM
70% 10:15AM
72% 10:22AM
74% 10:25AM
82% 10:49AM
84% 10:55AM
86% 11:00AM
92% 11:12AM
95% 11:25AM
97% 11:33AM
99% 11:45AM

Charging from 0%-40% appear to be very fast. The charging speed slowing down from 40%-100%.
I'll do a test again, to verify this.

I'm a seller, not suitable to be the thread owner. And I'm getting very busy lately.

Any experienced (and not mobile booster seller) forum user willing to take over and manage "Mobile booster user group"?

Added on January 23, 2011, 8:25 amThe mobile booster's internal battery is 3.7V, and it have to be stepped up to about 5V to output.

I guess it won't be 5000mAh after the step up process. Any E&E guy can do the math?
And I think the mobile booster not only charging the battery, but also need to power the running device. So, not full 500mA/1A go to the battery?

Added on January 23, 2011, 8:28 amA customer report that the KBC-L2B is very HOT while charging blackberry bold 9700, could it be possible that the 1A current output is too much to the device? Any user have this experience?
