In our increasingly mobile age, mobile power is a must. We
are increasingly dependent on mobile devices: tablet PC's, notebook computers,
music players, mobile phones, & c. But these devices are only as good as
their battery charge. And once a battery's power is exhausted, what you have is
no longer a high-tech gadget, but rather a grossly expensive paperweight.

I have tried experimenting with portable battery chargers:
One of those I bought is powered by two AA batteries. The unit itself was the
size of a large cigarette lighter; and, needless to say, "batteries not
included". So I bought a set of expensive lithium-ion rechargeable
batteries. However, two penlight batteries are unable to meet the power requirements
even of a mobile phone. Another one that I bought was a solar-powered charger.
After 24 hours of charging, it can fully charge a mobile phone (a Nokia 3310). However
this charger needs to store power in an internal battery (I opened it out of
curiosity). If the battery is out of juice it cannot recharge a device while it
is charging under the sun.
To be able to use my power-hungry mobile devices (thanks to
wireless Internet, large TFT screens, and mobile applications), on the go, I
had to buy a mobile power bank. There was even an instance when I was using my
tablet in class when the batteries conked out: What an embarrassing situation. And
the solution happened upon me with CD-R King's Mobile Powerbank (PWB-023-GHI).
Specifications: (from
the box)
With LED Flashlight
Input Voltage: 5.0 V / 1 A
Output Voltage: DC 5 V / 1.8 A
USB interface charger
Power Capacity: 5000 mAh
Supports: mobile phones, iPad, iPhone, iPod, and other USB
supported device
Dimensions: 75 x 58 x 21 mm
The first thing I noticed about the Mobile Power Bank is its
power capacity: a whooping 5000 mAh (milliampere-hours). For the uninitiated,
the ampere is a unit to measure current, i.e., how much electricity flows
through a given point. (By the way, the Tagalog word for "electricity",
kuryente, comes from the Spanish word
for current, corriente, instead of
the word for electricity, electricidad.)
For batteries (and capacitors), milliampere-hours are used for measuring
capacity, i.e., how much electricity something can carry (as opposed to
"voltage", which measures the strength of an electrical charge). Five
thousand mAh could easily meet the power needs of my mobile devices: I have a
couple of phones in the 1000+ mAh range and a tablet PC in the 3000+ mAh range.
This means I could probably recharge my tablet PC and have enough power left to
for at least one of my mobile phones.

Another thing that I noticed was its size. CD-R King has
another mobile power bank which is slimmer, similar to the size of an iPhone; but
that was rated at only 4000 mAh. So, for a few more bucks, I opted for one with
the higher capacity. The one with 5000 mAh was the about the size of a
cigarette pack.
Another thing I noticed was that it also has a LED bulb that
turns the power bank into a flashlight. I tried testing it while walking home
in our dark school campus. The bulb wasn't very bright; but with a battery with
5000 mAh, I wondered how many hours (days?) a single charge would last.
The Powerbank is recharged via USB charger through a mini B USB cable (included in the package). The USB charger was not included in the
package. Fortunately, I had one lying around (also from CD-R King) rated at
1000 mA. It takes an overnight charge to charge the Powerbank's batteries to
full.
The output is via a standard female USB outlet. The package only
includes a micro B USB cable; unlike the other power banks that includes a cable
with interchangeable pins. A device that uses any USB charging/data cable can
be used with the Mobile Powerbank.
The first test of my Mobile Powerbank is when during my bus
ride home from work. I used it to supply power to my Da Peng T2000. The
Powerbank was able to provide power to my phone while I was surfing the
Internet during my one hour commute. When I got home, it was able to fully
charge the phone's batteries in about four hours.
Another test of the Powerbank's capacity is when I charge
two 1000+ mAh mobile phones, one after the other. It was able to fully charge
the phones with plenty of power to spare.
The ultimate test of the Powerbank is to charge my tablet PC (tech review coming soon), whose batteries are rated at 3000+ mAh. I went to Burger King, my favorite
hangout for several reasons: the Whooper, large fries, large drink, and free
ice cream sundae, and for the free WiFi. I have been using my tablet for the whole
day. I began with 12% battery power, which would normally last maybe half an
hour. But plugged into the Powerbank, the tablet was able to last up to two
hours! It was not able to charge the tablet whilst in use probably because it
uses as much (or more) power at the rate that the Powerbank gives.
Overall, I find this product very good. I keep it in a
leather pouch in my bag so that when any of mobile devices run low on
batteries, I’d just plug it into the Mobile Powerbank and I’m off and running
again.

Iyong ibang Power Bank ng Cdr-King ay DI Worth(sulit) It.,
.
Bakit?
.
Una., Iyong Mah(capacity ng battery) na nakaindicate sa product ay di totoo,. mismo technician ng cdr-king nagsabi sa akin., pero kung ganun pa man dapat indicate nila ang totoo MAH
..,
Pangalawa, Matagal magcharge ang powerbank,. tapos ang bilis pa malowbat
.
Halimbawa:
Meron ako 14400 mah na CDR-KING POWER bank
Kaya nito magcharge ng 1000 mah NA BATTERY na 14 times pero base sa dry run test ko within 1 week ko nabili.,
Only 9000 mah lang kinaya..
.
fyi:almost 15 hours(full hour charge ng 14400 mah) ko chinarge ang powerbank
.
Gusto ko man ibalik pero parang mabibiwsit ka lang sa mga staff ng cdr-king dahil sa pagtanggi nila sa produkto nila na binili ko. Para sa akin,Magsasayang lang kau ng pera para sa mga powerbank nila.,Maari magamit mo man pero iyong pera na binayad mo para sa specification ng product nila ay hindi sulit.,
.
Last try na ako bibili ng powerbank ng cdr-king., Mas mabuti bumili ng branded kahit mahal, totoo ang MAH na nakaindicate doon at tumatagal.,
.
Gusto ko lang ishare sa inyo ito para di rin kau madisappoint pagdating ng araw
