External battery options

I need to have some extra power for my iphone 4 on my annual trip from Hawaii to South Carolina.
I don't want a case with a battery - just something I can plug into the phone externally. One that particularly intrigued me both because of relatively low cost and the ability to add to it is this:
http://www.amazon.com/Portable-Emergency-Battery-Charge-Extender/dp/B003TOOXQ6/r ef=sr112?ie=UTF8&qid=1288583778&sr=8-12
AA batteries can easily be carried or bought in an emergency. But, aside from any general comments people may make about this item, I'm particularly interested in three things:
1. Would rechargeable batteries work with it?
2. Regardless of rechargeable or not, would certain kinds of AA batteries be particularly good or bad?
3. Is there any comparable value in the combined mAh of AA batteries to the batteries that come with the phone? I know the iphone 4 battery is close to 1500 mAh. You can get AA batteries that are 2000 to close to 3000 mAh (I know those ratings are often overly generous, but that is not important). The thing is, do four 2000 mAh AA batteries mean I would have 8000 total, thus equivalent to the power of more than 5 of the built-in battery of the iphone?
Sounds too good to be true if it does.

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:

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?

Would Anker pro work as external battery for Macbook retina ?

Would Anker Pro 20000 mah work as an external battery for Macbook retina ? I saw a few other options like hyper juice and energizer but I'm looking for something under $100 and preferably portable.

X240 DO NOT HAVE Internal Battery, keypad backlit. 3 Cell External Battery only last for 2 hours!

Why does Lenovo dont tell about this missing features??
I bought the unit a day before I left the country, and then to my surprise it does not have the internal battery that Lenovo is boasting about. Fn+Spacebar doesnt work in lighting up the keypad and the 3-cell external batter is no way near to 4 hrs!
**bleep** hell Lenovo?
Another thing, is it possible to turn on the light (near the webcam) to light up the keyboard at all?

Hi,
1. Information about battery capacity for laptops with fixed configuration (i.e.not CTO) is provided in PSREF (for not all countries), on Lenovo support site in laptop model short description. It looks like the strings below:
6c Li-Ion
3c front battery and 3c rear battery
3c front battery and 6c rear battery
The 1st string is for 6 cell rear (external) battery.
If laptop is CTO the battery information is available in the purchase order or in the parts data base.
2. Keyboard backlight capability is optional feature. This information could be found in PSREF, in support site parts data base by laptop serial number.
3. ThinkLight feature is absent in Haswell based Lenovo Thinkpads.

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!

I'm going on a long trip. Is there an external battery for iPod?

I'm going on an 11 hour plane ride. My iPod 80GB may last 6 hours (movie watching). I did a seat search for airplane and there is not an outlet near my seat to recharge iPod. Is there an external battery or something that can be used on long trips so I can continue to watch movies?<

I just recently listed a few options in another thread. See here...

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?

Satellite A200 won't use external battery

Hi to all.
I have Satellite A200-PSAE6E, and I bought universal external battery. But external battery can't produce enough current for my laptop when internal battery is not full. When internal battery is full, external keeps it full and run laptop, but when internal battery isn't full and I plug in external battery, in a few seconds laptop shows that it is plugged in, and battery is charging, but after that few seconds, it shows only that laptop is plugged in, and battery doesn't charging.
Problem is that when laptop is plugged in and battery doesn't charging it use internal battery (like when it isn't plugged in), and when it empty internal battery it turn off, and there still shows that it is plugged in. Can I set that when laptop is plugged in, but doesn't charging it will use external power?
I am sure that is only software solution.

>This is universal external laptop battery. This battery produce 19V, and I don't see why Toshiba must recommend using this external battery?
Of course this is important because there is no guarantee that not supported and not recommended 3rd party options would be compatible with your notebook.
>I just need information if I can set that when laptop is plugged in but not charging, then laptop will use external power for its work, not for both (work and charging).
As far as I know this cannot be set. If the AC adaptor is connected to the notebook then the battery will charge automatically

What to look for when purchasing iPhone external battery?

Next month I’ll be taking a 5 day trip to NYC and I’ll be using my built-in iPhone 4 Google Maps GPS a lot, so I’m in the market to buy an external battery. So with that said, what should I look for when purchasing one? I’ve noticed a lot of these advertise the mAh (milliampere-hour), and then some will also advertise the amperes themselves (i.e. 5200 mAh (2 amps)). What’s the difference when they advertise both?

DVI support is a must and most LCDs in the size that you are looking for are going to have it.
Your MB can drive a display with a resolution of up to 1920 x 1200 which just happens to be the resolution of the 23" Apple Cinema HD Display. I didn't want to pay Apple prices for a display, so I went looking at Dell. I picked up a 20" 2007WFP display from them for about $360 shipped and it works like a charm with the Apple Mini-DVI to DVI adapter.
I prefer displays that use a S-IPS panel over the more common and cheaper TN panels. S-IPS is much better for color reproduction and that is why Apple uses them in their Cinema Displays. Dell uses the same panel is some of their 20" models - I got one - but some buyers are very upset that they got a TN panel instead of the S-IPS panel. I was lucky I guess.

Mac pro System Slows down without external Battery

All my app ,videos run very slow(Videos are most vulnerable) without external battery .However my battery charge shows 100 % ,mac pro 13inch Early 2011
can you please advise what could be the problem

Dose this issue happen when the computer is plugged in? or only when it's unplugged from power?
Have you checked for software updates? if so, have you installed all the updates? (apple menu, software update, install updates, reboot, repeate untill there are no more updates)
If the issue is happening while power is plugged in, have you tried a SMC Reset and NVRAM Reset?
Is there any thing externaly connected to the computer besides power? if so, haveyou tried removing those items; to see if the issue only happens while those devices are connected?
Do you know if yoru MacBook Pro has a NVIDIA GeForce 8600M GT? (apple menu, about this mac)
Do you have any kind of keyboard cover? if so, have you tried removing the keyboard cover, dose the issue still happen?
You could also try running an Apple Hardware Test. If it give you any error codes; I would suggest writing down the exact error message it displays.
Also it might be a good idea to set the graphic card to run on the high end card; and see if the issue still happens. (apple menu, system prefrences, energy saver, At the top there should be a check box along the lines of use best graphic performance at all time, check this box)

What is a good external battery pack for a 13" retina display?

what is a good external battery pack for my 13" retina display(macbook)

Have a look here for the sizes and prices.
It is however, much better to get a USB external drive that comes with it's own power adapter to avoid issues when or if your USB port can't supply enough power to your external drive.
That issue however does happen rarely but it does happen. Especially when connecting other devices to your other USB port while your external hard drive is connected to your other usb port.

Use of external battery cases, does it harm the iphone's internal battery?

Absolutely not, but if looking for a protective case i would not recommend the mophie but if just using your phone for commercial use, then yes definitely use, it's helpful when you need a cordless charger
