Ownership verified by DX last u a day without problem
Posted by Jovenrei on 3/14/2010
Involvement: General (knows how to use it) - Ownership: more than 1 month

Price: starstarstar
Ease of Use: starstarstarstar
Build Quality: starstarstar
Usefulness: starstarstarstar
Overall Rating: starstarstarstar

Pros: easy to use. can use it as addition batt for a day without any problems

Cons: at 1st, the batt lifespan is kinda long, and it can give my iphone a full 100% charge without any problem. As i uses it almost everyday for 1 mth plus, the batt level apparently drop quite significantly.

Other Thoughts: build quality can b better, but for the price of it, nothing much to complain.

Bottomline: as long as u give it a full charge when u leave ur house, it should have no problem giving u extra power for the rest of ur day.

Pros: can charge your iphone completely on its own.

Cons: quite bulky. LED light didn't work. Charge through didn't work.

Other Thoughts: .

Bottomline: It seems a new iphone OS upgrade has disabled passthrough charging. When I am charging with the phone connected, it charges the external battery first, the iphone goes on battery. When the charger is fully charged, then I insert the iphone with the cord on, the message "charging is not supported with this accessory" appears.

Ownership verified by DX Very good back up

Pros: 2400mAh battery... easy charge of phone.
does as described and is well worth the $30Aud
So good I bought 3 more. very reliable and it seems that the battery hasn't dropped off in 30 plus full charge discharge cycles.

Cons: Size and the sticker was like the previous reviw hanging off 1 of the 4 I bought.
I was disappointed that the top slide was not easily opeated. maybe a friction pad so it can be done.
Speaker is useless. do not buy this as a loud speaker.

Other Thoughts: excellent. easy use and fantastic back up.

Bottomline: buy it! Very good unit.

Pros: THIS IS AN EXCELLENT ITEM FOR THE TRAVELLER OR OUTDOORSMAN THAT FINDS THEMSELF AWAY FROM A POWER SOURCE FOR AN EXTENDED PERIOD OF TIME. ITS EASY TO USE AND CONVENIENT... KEEP IT PLUGGED INTO YOUR CAR CHARGER OR HOME.... IF YOUR ON THE RUN, JUST GRAB IT AND GET OUT....

Cons: IT IS A LITTLE ON THE BULKY SIDE... THE SPEAKER IS WEAK AND LACKS EVEN THE SMALLEST BIT OF BASS... THE 3 LED'S ON THE FRONT ARE ANNOYING, BUT WHATEVER, IF TELLS YOU THE STRENGTH LEFT.
THE BUILD QUALITY IS FAIR... THE COVER STRIP COVERING THE LED'S AND BUTTON WAS COMING OFF AT THE TIME I OPENED THE PACKAGE, HAD TO USE MY OWN DOUBLE SIDED TAPE TO FIX IT BACK IN PLACE.
I CAN SEE PROLONGED USE CAUSING PROBLEMS WITH THE PLUG ON THE IPHONE OR THE PLUG ON THE UNIT DUE TO ITS LACK OF MOVEMENT WHEN SLIDING THE PHONE IN. IT DOESNT SLIDE IN SMOOTH WHEN YOU SLIDE THE PHONE IN AND CLICK IT BACK.
ITS PRETTY DIFFICULT TO REMOVE THE PHONE WITH EASE... TAKES A LITTLE WORK...

Other Thoughts: ITS A GOOD BUY FOR THE PRICE, BUT IF YOU ARE LOOKING FOR A TOP QUALITY PRODUCT, CHECK AROUND....

Bottomline: "OK" PRICE FOR AN "OK" PRODUCT...
