Why Output Matters When Buying A Power Bank

External batteries come in all shapes and sizes, nowadays. They come with various additional features, cases made out of different materials, their storage capacities are smaller or larger, however, they also come with different output amperages.

While most may overlook this feature, the amperage is extremely important for two very distinct reasons:

  • Some devices require a particular voltage in order to charge effectively. Some don’t charge at all unless they receive the right amount of power, while others may break due to a lower or higher than specified current;
  • Amperage determines the speed at which your devices draw power from the external battery.

More is better, especially when charging high-performance devices

Most external batteries typically come with one of two USB output ports: 1A or 2A. These usually dictate the purpose of the powerbank test, as 1A is usually suited for smartphones and extremely power-efficient tablets, while 2A is the one to use for high-power tablets.

There are even devices that will leach the energy stored in a power bank, through a 1A port, but will not charge if used while connected. Newer models of power banks even come with A2.4 output ports that can charge a phone in a couple of hours and a tablet in 3-4 hours.

However, it is important to remember that some devices cannot benefit from the greater amperage and will not charge faster, no matter what kind of output port an external battery has. It’s usually best to look at the device specifications prior to making a purchase.

Furthermore, some external batteries have a feature that will identify the capacity of your device’s battery and will choose what amperage to deliver in order to charge it. This system does not require a particular output port, as the power bank’s controller will regulate the power flow.

The reason why I dislike Vista

As it stands you would believe I own some massive 3 story super-computer that can do everything but brew my coffee in the morning. However, as it stands I actually own a Dell Inspiron 1525 which I am learning to hate the more I use it.

With some good specs – 15.4 inch screen, 2.0Ghz Duo Processor, 3GB SDRAM, Integrated Webcam, and only weighing 5.9 lbs. Great – just a few problems. The inlaid glossy screen is not flawless. Viewing angles can cause the colors to invert, making it impossible to see. Unless you have it set at the perfect angle in comparison to the light – your monitor will upchuck a bunch of nothing for your viewing pleasure. There also is no dedicated graphics card – not even an entry level nVidia. This laptop is great for productivity but not for high end 3D graphic usage. It just clunks out. It’s a mediocre computer for $700 after taxes.

My real issue truly is not so much Dell or their lack of comprehension in designing a laptop that goes beyond basic functionality. It is the operating system – Windows Vista. Get it, got it, fuck!

So what is so maddening about Windows Vista?

 

Windows Vista
Clearly it’s probably one of the million pop-up boxes asking my permission to unzip a file, move a fie, rename a file, refresh the desktop, use the bathroom, and take a shower. Pop-ups in general annoy me to no end. Vista just pisses me off.
In reference to my latest post Firefox Burns Internet Explorer – what is Microsoft’s issue in designing a platform that can handle the occasional bug or lock-up without having everything within a 4 mile radius freeze and crash too? This is an obvious fluke in the core design.
There just isn’t a damn thing that caters to user based scenarios. Microsoft yelps “It’s secure, what else do you want? Accessibility? User friendly?” – Linux and Mac managed to not bug this one up. However, Microsoft takes a different tact and makes UAC the most obtrusive flipp’n thing you’ve ever seen.

Rob Williams had me nodding in agreement with his article: Top 8 Vista Annoyances

Edward and Eric at PC World summed all my ripping thoughts up in their article: The Most Annoying Things About Windows Vista

The most entertaining of it all “The Downgraded Upgraded Disc” – seriously? Another solid point I can’t believe I overlooked – but Edward and Eric are right … just moving around furniture doesn’t make it new again.

“Who Rearranged the Furniture?
Here’s a note for the programmers working on the next version of Windows: Moving stuff around doesn’t necessarily make it better, just harder to find. Vista’s chock-full of settings and tools that have been rearranged, renamed, or reorganized for no apparent reason.”

A great annoyance – forget gaming on Vista. Just ain’t happening! Maybe the donkeys working on Vista should consider the upgraded – downgrade disc… I will preorder one.
