Seeking external battery source

I fly back and forth from the east to the west coast for work and would like to purchase an external battery source for my mac. Problem is most of the ones online don't specify if they have an adapter for a mac.
Does anyone here have any suggestions on what I can look for online that would work for maybe a 4-5 hour external battery source?

I'm looking for exactly the same product. It's very annoying to have to change batteries: charging the second battery is a hassle and you have to shut down the computer to replace it. Having an external battery makes much more sense to me...
I found two options worth while checking out:
http://www.quickertek.com/
http://www.batterygeek.net/
However, I would prefer an Apple solution, with the aesthetics and ease of use that Apple typically provides.
Is anybody at Apple listening?

  • External Portable Battery Source Recommendations?

    I am looking for an external power source to set next my computer on a card table outdoors. I was looking for something you could just plug the existing Apple battery charging wall socket cord into and attach the other end to the MacBook Pro. The power source has to be protable - I'd like to carry it in my existing large laptop portfolio bag if possible so I am not really looking for a emergency backup supply. The existing battery works great, but lasts about 3 hours - I'd like to see 8 hours.
    MacBook Pro 15" Late 2008 2.53 Dual Core 8GB Memory (OWC Upgrade from 4GB)

    Antifor: In case you find the Hypershop web site as disorganized and confusing as I did, just scroll directly to the bottom of the page wjosten has linked to see their lineup of external battery packs.

  • Sharepoint 2013 Excel External Data Source Refresh Issue

    I have been facing this issue for quite some time now.. i have created an Excel sheet in Excel-13 and have imported data from an external data source [SQL server 2012]. 
    Everything is working fine, with the excel sheet on the desktop. Data refreshes, every-time i open the excel file and also at regular intervals that i have configured in the data source properties.
    The problem begins when i save that excel sheet on my sharepoint server. the issues that i am facing are :
    1. Changes made into the original data source, are not reflected immediately inside the excel sheet inside the browser. after 5-10 minutes, it reflects the changes..
    2. The data doesn't refreshes automatically. After i update my data inside the sql server table, i have to manually trigger the refresh of the data connection when viewing the excel sheet inside the browser, even though i have marked "Refresh when opening
    the file", and refresh every 1 minute inside the excel sheet. Any solutions ??
    I have been troubled a lot by this issue, and seek for some quick solution.. Any help here ??

    I found the solution finally, my self ..
    Issue - 1 : It's going to take atleat 5-minutes to refresh the data connection, that is generally not a big time span.
    Issue - 2 : 
    --> Set Your connection to refresh everytime the file is opened. go to internet explorer -> file -> internet options -> general -> Browsing History -> Settings -> Check for newer versions of stored pages... Check 'Every time I visit the
    webpage'. 
    Now everytime i update your original data source, wait for 5-10 minutes and refresh my web page containing the excel sheet.. The Contents of the excel sheet are updated as desired..

  • Is there a MagSafe 2 compatible portable external power source for the retina display MacBook Pro?

    I’m using a retina display MacBook Pro with the MagSafe 2 connection.   I would like to have a portable external power source to extend the use of my laptop on long field trips where I am away from power sources. Swapping batteries is not an option for this generation of MacBook Pros.  There seem to be many options for PC’s and even iPhones/iPads/iPods but the MagSafe 2 connection seems to be the issue.  I saw one link that suggested buying an Apple MagSafe 2 power adapter and performing surgery on the power cord (using components provided by the vendor) so that the adapter would run on their back up battery.  I was hoping for a more esthetically pleasing solution. Any suggestions?  Does this product exist and I just missed it? Clearly, if a MagSafe(1) compatible external battery existed I could adapt that using the MagSafe to MagSafe 2 converter.

    Sparon,
    I wouldn’t recommend using an underpowered AC adapter with your MacBook Pro. It sounds as though the best solution would be to get a different laptop bag with a sufficiently large side pocket.

  • Power settings for an external battery

    I'm using an external hyperjuice battery, which connects via the magsafe power socket.
    It's identified in OSX power settings as Power Source: Power Adapter
    so it's draining power as if on mains electricity.
    If I could set it to work as a battery, it would last longer... but OSX doesn't seem to give me the option to choose what power source I use.
    Best I can do so far is to tweek Mains Power settings to act like a Battery; is there a way of forcing OSX to sip power at battery levels, when connected to the external battery?

    Thanks Jerry for your advice. I have had for a week a 22" ViewSonic connected with a HDMI Mini Display port adapter. I tried to do my best for the setup of this monitor with 1080p resolution while the MBP 13" was setup to the native resolution 1280X800 but the image at the external display was not good enough as the MBP screen. In any case I have return the ViewSonic because other problems. I'm now looking for an other monitor but I'm not sure what to look for. I need for a bigger work space for Final Cut but with a good quality image. Do you have any advice?

  • Apple iPod shuffle External Battery Pack

    Has anyone used this? It sounds like a cool idea especially for travelling where I can't recharge. does it use just regualr AA batteries? (on Amazon, it says AA in one place and AAA in another.)
    And I read some reviews that said it ruined their Shuffle just by plugging it in. Any experience with that?
    thanks for any advice.

  • What is the best external battery to use with a macbook pro retina?

    Looking for the best option here. What is the best external battery to use with a macbook pro retina?

    You should check your date of purchase against the manufacturer's warranty
    or guaranty since some of those better brands have some recourse should
    they fail within a specified time period. A good reason to save dated receipts.
    Since solid-state USB drives probably don't (all) use a wear-leveling software
    to equally utilize their recordable space evenly, it is possible that some of these
    may exhibit a failure in some sector areas due to excessive over-writing. If the
    ones you use do not have such a technology or an undercounted total capacity
    with a means to automatically write in other sections, you may have to consider
    manually using a disk utility to zero-overwrite and reformat them occasionally.
    Even so, that may only help a marginal flash or thumb drive work a little longer.
    Should a camera memory card fail you still may be able to attempt with margin of
    success, to +recover image files+ from it. re: http://www.cgsecurity.org/wiki/PhotoRec
    The standard default format they ship with works well for most file types; so if
    you aren't moving OS X or Mac app specific files around on a USB flash drive,
    the original format should be fine. Oh, you can use Disk Utility to attempt to do
    a repair; but in some cases you may have to reformat them, etc.
    {Some of the flash drive warranties or guarantees may vary from between regions;
    so if you have one with a '5 Year' guarantee in the US, other rules may apply in EU,
    or when you seek to replace an item under warranty outside of where it was bought.}
    Good luck & happy computing!

  • IPOD External battery

    I wanted to know if the IPOD well stop charging once the battery is full? I also wanted to know if using an external battery exclusively like a power-bank well affects my battery life. I have no problem with cliping my power-bank external battery pack to my belt with my Ipod, but well it result with problems. Thank You..

    the iPod will stop charging once the battery is full. There should be no problem with your external source assuming it is iPod compatible for your model.

  • Charging iPAD Battery from External Battery

    Question:
    When you plug in a Hypermac (third battery) battery to an iPad, does it charge the iPad, or does the iPad run from the external battery.
    I have seen documentation that says, if the iPad battery is dead (less than 10%), then the external battery will charge the iPad to a "certain level", and then the iPad will run from the external battery.
    Can anyone provide guidance and or Technical documentation regarding this ?
    thanks,
    Wilson

    Yes the iPad expects a constant voltage input of 5 Volt. The maximum charge current is 2.1 Ampere. The internal battery is charged by an intelligent charger, there is no direct connection between the external power and the iPad battery. Charging Lithium based batteries isn't trivial. Below a certain voltage the charge current has to be pretty low. When the battery is completely drained the charger will start with a lower rate. Once it reaches a certain voltage the full 2.1 Amp are charging the battery. As the internal battery is 'filling up' the voltage goes up. Once it reaches a certain level (4.2 or something around that, depending on temerature) the charger has to reduce the current (Ampere) gradually to make sure the internal battery's voltage never goes beyond that level. Letting it go higher is what makes those batteries explode.
    All this is completely separate and independent of the external power supply. The iPad expects a constant 5 Volt and it will draw as much current as it needs or the supply allows. All external batteries that are sold as i-device chargers have a regulated output. The output voltage is constant (5 Volt) regardless of the battery level or voltage. The majority of these have a 500 mA or 1 A limit, only a few newer models are now equipped with regulators that are capable of 2 Amp. So only those will allow the iPad to charge as fast is it's possible. But again, the output is a regulated constant voltage.
    I'm pretty sure the iPad would not even start charging if the external power is an unregulated source like a direct connection to a battery.

  • Multiple AD External Identity Sources in ISE 1.2

    First I guess is it possible to have multiple AD entries for External Identity Sources in ISE 1.2? When I display Active Directory (AD1) it displays my four ISE servers with a status of connected but I see no where to add anything additional. I did not originally set this up so figure I am missing something somewhere if this is possible. I though maybe add under LDAP and then it would roll into AD or something but I have nothing listed under LDAP either.
    What I am trying to do is figure out how to have ISE cover our two different domains. We ahve one big forest but currently that is split into two AD domains based upon our two divisions.  am trying to see if possibly I can simply get through the existing configuration to pull security groups from the other domain into the dictionary but so far that has proven not do able.
    Brent

    Saurav,
    I was beginning to think that might be the solution. Now I just need to go through the release notes and make sure there are no issues with it running on ACS-2111 appliance. We are currently using this as the secondary Admin but knew we would have to move off something. I think management is hoping later than sooner especially since we are still in that initial roll out phase.
    How does the system handle the fact that this is all centralized but I have users authenticating from the different time zones? I have been reading about everything pointing to the same NTP server but took that to simply be the servers in the ISE Cluster. Will this also impact all the switches and network devices involved in the authentication process?

    For #5, not Windows, ConfigMgr 2012 R2. Anything before ConfigMgr 2012 R2 is not supported for the 8.1 ADK.
    For the permissions, what accounts are you setting this for. In general, if the share is on the same server, Everyone Full or Read on the Share and System Full or Read on the NTFS should work.
    For the error message, it looks like you are trying to import an OS Image and not an OS Install Package. OS images use a WIM file and OS Install Packages use the entire set of source files from the media. For OS images, you must thus explicitly point it
    to a specific WIM file.

  • Excel SSAS Tabular error: An error occurred during an attempt to establish a connection to the external data source

    Hello there,
    I have an Excel report I created which works perfectly fine on my dev environment, but fails on my test environment when I try to do a data refresh.
    The key difference between both dev and test environments is that in dev, everything is installed in one server:
    SharePoint 2013
    SQL 2012: Database Instance, SSAS Instance, SSRS for SharePoint, SSAS POWERPIVOT instance (Powerpivot for SharePoint).
    In my test and production environments, the architecture is different:
    SQL DB Servers in High Availability (irrelevant for this report since it is connecting to the tabular model, just FYI)
    SQL SSAS Tabular server (contains a tabular model that processes data from the SQL DBs).
    2x SharePoint Application Servers (we installed both SSRS and PowerPivot for SharePoint on these servers)
    2x SharePoint FrontEnd Servers (contain the SSRS and PowerPivot add-ins).
    Now in dev, test and production, I can run PowerPivot reports that have been created in SharePoint without any issues. Those reports can access the SSAS Tabular model without any issues, and perform data refresh and OLAP functions (slicing, dicing, etc).
    The problem is with Excel reports (i.e. .xlsx files) uploaded to SharePoint. While I can open them, I am having a hard time performing a data refresh. The error I get is:
    "An error occurred during an attempt to establish a connection to the external data source [...]"
    I ran SQL Profiler on my SSAS Server where the Tabular instance is and I noticed that every time I try to perform a data refresh, I get the following entries:
    Every time I try to perform a data refresh, two entries under the user name ANONYMOUS LOGON.
    Since things work without any issues on my single-server dev environment, I tried running SQL Server Profiler there as well to see what I get.
    As you can see from the above, in the dev environment the query runs without any issues and the user name logged is in fact my username from the dev environment domain. I also have a separated user for the test domain, and another for the production domain.
    Now upon some preliminary investigation I believe this has something to do with the data connection settings in Excel and the usage (or no usage) of secure store. This is what I can vouch for so far:
    Library containing reports is configured as trusted in SharePoint Central Admin.
    Library containing data connections is configured as trusted in SharePoint Central Admin.
    The Data Provider referenced in the Excel report (MSOLAP.5) is configured as trusted in SharePoint Central Admin.
    In the Excel report, the Excel Services authentication settings is set as "use authenticated user's account". This wortks fine in the DEV environment.
    Concerning SecureStore, PowerPivot Configurator has configured it the PowerPivotUnnattendedAccount application ID in all the environments. There is
    NO configuration of an Application ID for Excel Services in any of the environments (Dev, test or production). Altough I reckon this is where the solution lies, I am not 100% sure as to why it fails in test and prod. But as I read what I am
    writing, I reckon this is because of the authentication "hops" through servers. Am I right in my assumption?
    Could someone please advise what am I doing wrong in this case? If it is the fact that I am missing an Secure Store entry for Excel Services, I am wondering if someone could advise me on how to set ip up? My confusion is around the "Target Application
    Type" setting.
    Thank you for your time.
    Regards,
    P.

    Hi Rameshwar,
    PowerPivot workbooks contain embedded data connections. To support workbook interaction through slicers and filters, Excel Services must be configured to allow external data access through embedded connection information. External data access is required
    for retrieving PowerPivot data that is loaded on PowerPivot servers in the farm. Please refer to the steps below to solve this issue:
    In Central Administration, in Application Management, click Manage service applications.
    Click Excel Services Application.
    Click Trusted File Location.
    Click http:// or the location you want to configure.
    In External Data, in Allow External Data, click Trusted data connection libraries and embedded.
    Click OK.
    For more information, please see:
    Create a trusted location for PowerPivot sites in Central Administration:
    http://msdn.microsoft.com/en-us/library/ee637428.aspx
    Another reason is Excel Services returns this error when you query PowerPivot data in an Excel workbook that is published to SharePoint, and the SharePoint environment does not have a PowerPivot for SharePoint server, or the SQL Server Analysis
    Services (PowerPivot) service is stopped. Please check this document:
    http://technet.microsoft.com/en-us/library/ff487858(v=sql.110).aspx
    Finally, here is a good article regarding how to troubleshoot PowerPivot data refresh for your reference. Please see:

  • Can I use an external battery pack on my 17" Mac Book Pro?

    Hi
    This may sound like a crazy question, but is it possible to safely use an external battery pack on my Mac Book Pro?.....specifically a Bescor Video Light battery pack which I can just plug my a/c power cable into. This would be very useful in the case of a local power failure (which actually may just happen tonight, as we are currently in the middle of a blizzard).
    Just wondering......
    Thanks,
    Anneita

    Yes, you can use external battery packs — but I wouldn't use one that I wasn't perfectly certain was very carefully controlled.
    External battery packs specifically designed for MBPs:

    Another option, designed to protect sensitive equipment from power surges and enable uninterrupted computer usage during AC power outages and irregularities, is called an +uninterruptible power supply,+ and the leading manufacturer of such devices — which incorporate storage batteries of various capacities — is APC:
