A long, long time ago, I fell in love with a Mac Book Air…but I couldn’t pull the trigger. $1800 was just too much for a laptop. So, I waited, and waited, and waited. And just before the second version of the MacBook Air came out, I bought a refurb Rev A MacBook Air. It was my primary computer for a LONG time.
It wasn’t fast. Flash slowed my CPU to a crawl. The hard drive was little (80GB) and slow (4200 RPM), but I loved that computer anyway. It was a trusty computer, even for a refurb. It went with me wherever I went.
But times changed, and I started using a 27″ iMac as my daily computer and my little MacBook Air only came out when I was on a train or a plane. But the MBA started to creak and moan a little too much, so I bought a new computer for traveling…11.6-Inch MacBook Air. And it was love at first boot. The computer is fast and graceful, and so tiny that it truly can go anywhere that you do. You never have to think about bringing your computer with you or not…it is so small that it isn’t a consideration to NOT bring it. I will be also talking about high quality power banks that I brought from India and other gadgets later in this article.
Old MacBook Air:
- Thin, light and easy to take with you.
- A “real” computer…not a netbook. No compromises with displays or functionality.
- Good battery life.
- Battery life was just “good”. I still need to take a charger with me.
- 13.3″ is too big for most airline seats.
- Slow to start (waited a long time to wake up from sleep, slow connecting to WiFi).
- Long boot times.
- Long time to load apps.
- Creaked under 2GB RAM (or so I thought).
- Video playback is sketchy.
New MacBook Air
- Speed – fast to boot, fast to wake up, fast to launch apps. (I thought the speed issues in my Rev A were RAM related? Now I am sure it is the poky hard drive).
- Size – this is so small that I never think “Should I take it with me?” Fits comfortably in any airline tray.
- Screen – Higher resolution, I think, than original MBA. Rented a movie (Scott Pilgrim…very good…fun flick) and and watched it with no fatigue…beautiful display.
- Great video playback.
- Great battery life (a real 5 hours…I still need to take a charger, but now it is for emergencies…)
- Great sound for such a small laptop.
The difference in price? I paid $999 for my refurb Rev A. I paid about $1149 for my brand new MBA. The difference between these two is far more than $150. The real difference is 2 years. Time has solved so many of the issues that plagued my original MBA. The new MBA is just a delicious machine. I can’t tell you how much more I use it that I used my Rev A. My iMac is feeling neglected.
Choosing Power banks in India
Power banks are portable device that is nothing but store electrical energy and can be use to power you smartphones and other gadgets on the move. Before you buy a powerbank — aka portable battery charger — check for the mAh capacity mentioned on your smartphone battery or the specs in your mobile’s manual (in the case of non-removable batteries). For instance, if your device has a 2000mAh battery capacity, buy a power bank with at least 2500mAh. But there are power banks in our round-up that are technically superior, with LCD screens, faster and mutliple inputs and outputs, support for USB-C, AC outlets, higher capacity, waterproofing and so forth. Of course, without energy, these so smart, and so expensive devices are useless and worth as much as paperweights. While you can get one with a higher capacity (there are battery packs which go up to 20,000mAh) so that it’s able to recharge a device multiple times over, keep in mind that this usually also means that it’s bigger, heavier, and pricier. If you buy a 4500mAh model, it means you can charge your 2000mAh phone at least twice.
- Some of this stuff you almost certainly don’t need, but if it comes at a good price we bet you’ll want it.
- So, power bank can serve this purpose perfectly.
- Most smartphone-oriented battery packs output at most 1A (at 5V) over the USB port.
- In any case, opt for the highest capacity that your budget allows.
- It has enough capacity for several charges and it’s great value.
- It could energize your devices back to life and prolong the usage of your devices for hours.
While this works fine for most people, some may notice that their smartphone now takes a longer time to recharge as compared to when a wall charger is used. Though many power bank buying guides will advise you to buy the biggest possible battery capacity in your budget, we would strongly advise you to hold your horses. A well worthy winner of our best power bank crown. The question is ‘how do you know which one is the right power bank for you?’ If you search on eBay, you could find a lot of different styles, different specifications of power banks.
Instead of plugging your charging cable into the wall, you instead plug the charging cable into the battery pack and fill up the device’s batteries that way. Some tradeoffs are also involved with bigger battery capacities. A little expensive as compared to lithium ion, it is lighter in weight, and has better safety features and performance. It looks confusing, right? Not all battery packs are created equal, however, and even if the build quality is good, you can easily end up with an external battery pack that doesn’t fit your application and power needs.
How to choose power bank for your phone and tablet? On the other hand Lithium ion, ( 18650 Lithium Battery) which is 65 mm in length with a diameter of 18 mm, is cylindrical in shape and, despite being old school is still popular due to its low price. Actually, it is not that hard, if you follow my recommendations. Portable Power Banks will help us to do that and will maintain the consistence of our electronic devices. Surely, it could be easy for you as you could just follow these tips below one by one; while it would be a little hard as you have to read and check the tips carefully, covering up to eight aspects in total, the size/capacity of power bank, power output, number of USB ports, cables included, power input, safety, quality and certification.
Like you, we have been confused and then frustrated as we bought some duds that just stopped working after awhile. Your battery charger specification is located on the usb adapter bundled with your device. In this article we will get you a list of Portable Power Banks which are best in use. And when we returned to the mall, the shop was gone for good. For most Smartphone batteries, the output voltage is 5V and the current is 1A/2A.
No of ports
These devices are most trusted with 100 percent efficiency. It was a fly-by-night business selling numerous fake and low grade power banks. Higher the current,faster it will charge your battery. So have a look at each Portable Power Banks and find one best for your devices. A simple walkthrough Lowyat, Digital Mall and even the shop near your house shows you that the trend still exists.
Whilst smaller is better for portability, bigger could be more important when it comes to capacity. Choose the best company and the standby capacity based on your requirements. Powerbank capacity is measured in “milli ampere hours” (mah) and different models range from 2,000mah to 20,000mah. For practical purposes, charging an iPhone 5 needs a capacity of about 1,600mah so if you want to charge it once, you’d buy a powerbank with 1,600mah capacity. If you want to charge it twice, you’d need a powerbank with a capacity of about 3,200mah or more.
External hard drives
The other drive I bought is 1 Tb external hard drive. If you are looking to buy the best external hard drive in India, then continue reading this guide.External hard drives are the answer, giving you plenty of cheap and cheerful storage or an extra high-performance drive in a convenient, easy-to-use package. Storage performance refers to the speed at which data transfers within a device or from one device to another. A smart size for people looking to store videos would be 1TB or 2TB. There are generally two types of external hard drives: solid-state drives (SSD) and hard disk drives (HDD). Solid-state drives, although extremely fast, are also extraordinarily expensive. Now that USB 3 and USB Type-C are pretty much ubiquitous, they’re up to handling the most demanding applications too, including 4K video and games.
- Currently, the speed of a single consumer-grade internal drive is largely defined by the Serial ATA interface standard (aka SATA). This determines how fast internal drives connect to a host (such as a personal computer or a server) or to one another.
- If you’re mostly just storing emails and word documents, a smaller one could do.
- You can pay nearly triple that of an external HDD when you start getting into large capacities.
- Here we’ve picked out some of the best to cover every need and budget, including both slimline portable and beefy desktop drives.
- Unfortunately, many computers are equipped with a meager 1TB of disk space, some of which is already taken up by the operating system.
- The more files you want to store, and the larger the file type (photos and videos are larger than word documents), the bigger you should go.
Although an external SSD is safer because it has no moving parts, you should be OK with an HDD as long as you don’t treat it like a maraca when you’re transferring files. Hook one up and give yourself a little room to breathe. Apart from that, computers are still far from perfect and will often fail at the most inconvenient times, so it always helps to have a backup of all your most important files. The amount of space needed for your files is a matter of both quantity and quality.
External hard drives are also great ways to easily upgrade the storage capacities of your devices. Desktop-class models currently top out at 8TB per mechanism, but some drive manufacturers put two or more mechanisms into a chassis for more storage (for example, two 4TB drives for a total of 8TB of storage). Notebook-class drives come in capacities up to 4TB, but capacities from 500GB to 2TB are most common. There is the sheer number of accumulating files (documents, e-mail, digital photos, software programs, music, tax records, apps, videos, games, and all the rest), but individual file size is also part of the equation. The best external drives will be portable, with large capacities and robust designs that keeps your data safe when they are being moved around. Once you’ve decided between an HDD and SSD, you have to pick a form factor.
With media files in particular, better picture and sound quality means larger files. Do you need to be able to access files when you are on the move but only use one or two devices? Thankfully, there are only two choices and the right choice will mostly be dictated by your current setup. For instance, the photos and videos captured by a 20-megapixel DSLR will take up more space than those from a 10-megapixel point-and-shoot camera. You may wish to consider a portable hard drive or USB flash drive.
Don’t worry, this decision will be easy. Desktop drives are designed to stay in one place, usually on your work surface at home or at the office. Do you regularly work in one location using heavy files such as photographs and video? If you’re buying a desktop-style drive for active use (video or lots of file transfers), look for one with a built-in fan, as the extra cooling will extend the drive’s life expectancy. If so, you may need the kind of storage capacity that only a desktop hard drive can offer. More compact notebook-class hard drives are usually 2.5in disks powered through the connector cable without the need for a power adapter.
