5.0 out of 5 stars INVALUABLE TO POWER DASH CAM, 27 Jan 2014
Verified Purchase(What is this?)
This review is from: TeckNetŪ POWER BANK 15000mAh USB External Battery Backup Pack, Mobile Phone Power Pack, High Capacity Portable Battery Charger (Dual 5V 3.1A USB Output) for Apple iPhone 5S/5C/5, iPad mini 2/1, iPad 5/4 (Lightning Cable not Provided), iPhone 4S, iPad 3/2/1; Samsung Galaxy S4, S3, Ace, Note 3/2; HTC One, Sensation, Desire C S X, Wildfire S; Google Nexus 7, Nexus 10; Nokia Lumia 920 800 900 N8; Motorola Razr; LG Optimus; Blackberry Z10; Sony Xperia Z - Black (Wireless Phone Accessory)
I use my TeckNet Power Bank 15000mAh to run my old iPhone 4 as a dash cam using an app called Witness. The phones built in battery last less than 2 hours when used for this purpose and it's not possible, for various reasons, to effectively keep the phones video camera running when plugged in to the 12 volt. I therefore decided to invest in this TechNet device having experimented with a 2300mAh clip on backup battery. And what a success it is! The Power Bank will sit happily in the corner of my dash on a sticky pad below the windscreen whilst connected to the iPhone using a standard charge/data cable which is for the best part concealed behind the A pillar trim. The phone is then running as a video camera for 10 to 11 hours a day and runs without a hitch for over two days, so well over 20 hours, before I then recharge the Power Bank - even then the Power Bank isn't fully discharged & whilst running the iPhone's video will keep the phone fully charged. To me this Power Bank is invaluable & well recommended.
