7/9/2016 - Asus X52D Battery

You should be able to get a good powerbank for $20 to $40. This should be enough to get a unit with dual USB output rated at 2A or more, with capacity ranging from 10,000mAh to 20,000mAh, and Quick Charge support to boot. Many are based on 18650 batteries, so a unit with four 18650 cells on average delivers 10,000mAh, which is enough tocharge an average phone three or four times. Some DIY designs also allow you to charge 18650 cells, which comes in handy if you have other devices compatible with these cells (flashlights, laser pointers, bicycle lights, and so on).While many people may not be familiar with this battery standard, it’s actually been around for ages. Laptop batteries of yesteryear were basically three to eight 18650 cells soldered to each other, so chances are, you already used them without even knowing.

A lot of new powerbanks also support Quick Charge, USB Type-C output, while others feature integrated wireless chargers. Also, if you’re an iPhone user, or use a big-brand Android device, you should have no trouble getting ruggedized cases with an integrated battery, which will protect your device and give you an extra day of battery life. All items listed above should weigh just a few hundred grams and take up a little space in your bag, provided you organize them properly. Their overall cost, save for the spare phone or router, should be around $100. A secondary dual-SIM phone should add about $150 to the total. All of these items are readily available online, via Amazon, eBay, or Chinese e-commerce platforms like AliExpress.

I took the liberty of including a few bits that aren’t directly related to productivity, such as memory cards and corresponding adapters, since I assume most don’t rely solely on their smartphones for photography. I did not include toys and gadgets that many of us take to the beach, like action cameras or fitness trackers, but much of the travel hardware listed above should help you deal with them as well.But what if you want a bit more? Well, having a secondary computer is always a good idea. I’m a fan of redundancy, and I hate having to sort out hardware issues on the road. At today’s prices, you just need a few hundred bucks to get a good Atom-based backup machine, provided you don’t insist on using a MacBook all the way. The same goes for smartphones. It’s always good to have a backup, but more importantly, a cheap dual-SIM phone can be used for tethering.

If your smartphone’s or laptop’s battery is running out of juice, you usually tend to charge it or switch to battery saving mode. You would never even think of it as a problem or a security threat, especially to your privacy. However, a new study on certain APIs has highlighted that the issue could be more than what it calls for.
According to a study by some researchers at the Princeton University, the battery status on your electronic device could trigger an event where your privacy could be at stake, online. However, the present study does not confirm whether the issue has been used for any sort of hacking, or privacy theft, but the results could be devastating.

Since your battery reports back to the operating system about the status of the existing power using APIs built into the software, it very well means that the software is using this information to trigger something. The something could be a battery saving mode, other than simply alerting you that there is ‘x’ amount of time remaining till the hardware shuts down. This simple and miniscule information from the battery can trigger something disastrous if misused. And this has been found by some security researchers.

Many internet users can be targeted from the websites they hit. Researchers at the Princeton University have found out that a small number of websites are now tracking devices with information about how much power or charge is left on the battery.As for now, it is not known how the websites are making use of the said information from the battery API. This could, however, be put to use by rogue websites for tracking information from users. The data can be used for targeted ads, products, etc, which could throw the user into websites plagued with viruses and malware.

Over the years, Asus has managed to come up with some really fine laptops sprawling in different categories. From the powerful R.O.G series to the beautifully designed Zenbook, most of the company’s notebooks/ laptops have been decently popular amongst most tech buffs and consumers. That said, the company recently came up with a new entry–level gaming laptop: Asus R510J.
This is not the first Asus notebook that I am reviewing and it’s definitely not the best one, however, it doesn’t take anything away from the fact that the idea to come up with an entry-level gaming laptop is great, especially in a market where gaming laptops are usually priced quite high. Well, now everyday gamers—looking for a mix of good computing and gaming—can rejoice with the inception of the R510J.

With this new laptop, Asus have intelligently tried to re-brand a powerful utility laptop as an entry-level gaming machine and there is nothing wrong about it. The laptop comes around with features such as an FHD display, 2.66GHz processor, 8GB RAM, and a powerful Nvidia GTX 950M for smooth gaming and multimedia experience.
After spending almost a week with the device, I am going to explain why exactly this laptop can become an absolute favorite among the PC/laptop gaming fraternity. So without further do, let's see if this budget-gaming laptop has the juice required to serve the purpose.

Design and Display: As I pointed out earlier, the Asus R510J is marketed as a gaming laptop, but it is actually a high-end utility laptop or a downgraded version of the company’s R.O.G series. In terms of the design, the laptop does look pretty attractive with it's attractive red and black tribal-centric graphic pattern on the lid, and also on the insides to attract gamers.The tribal graphic pattern on the Asus R510J makes it attractive and more gaming-centric. I feel that the graphics could have been a little more animated, considering the fact that it is branded as a gaming laptop. One minor issue with the design is the glossiness of the lid, which easily attracts smudges and fingerprints. Moving on, the laptop is quite sleek, albeit it's hefty 2.4kg weight. I did not face many problems carrying this around while work, and is quite handy and portable.

Opening the lid reveals a 15.6-inch LED backlit FHD display (1080x1920) resolution along with anti-glare function. The screen viewing angles are fairly decent, but could have been a lot better, as this laptop doesn’t support an IPS display panel. In terms of brightness and contrast, the laptop offers decently high levels for viewing in all lighting conditions.
The Asus R510J could have offered slightly better responsive keys, as gaming might get tough on the ones used.
Just below the screen is the spacious matte finished area housing the keys and the trackpad. As mentioned earlier, the insides also accompany the same tribal-patterned design in red and black.

One of the most disappointing factor from a gaming laptop perspective is the fact that the R510J doesn’t have a backlit keyboard, which is surprising. With the advent of myriad modern gaming laptops, backlit keyboards are indispensable on any gaming notebook.The Asus R510J does not employ backlit keyboard, which is disappointing considering it's price.
Another thing I did not like about the keyboard is the sponginess of the keys, which is all right for normal typing, but is very difficult to use while gaming. According to me, the perfect gaming laptop is not only about a good GPU and processor; it requires perfect aesthetics as well. Coming to the trackpad on this laptop, it is really smooth and great for completing tasks quickly. However, the only problem that I encountered is differentiating between the left and right touch on the pad.
On both sides of the laptop, you can find the usual connectivity options such as the USB ports, DVD writer, headphone/microphone jack, LAN and HDMI ports. There are notification lights along the bottom edge of the device, indicating battery, Internet connectivity, and a few more along with the SD card reader. One major disappointment is the VGA webcam. Even laptops fairing much below in contrast to the R510J feature HD webcams, and I feel that the company should have incorporated an HD one instead of VGA. All in all, the laptop looks decently attractive and does hint out at gamers, however, there are many other laptops in the market with superior design and aesthetics. Honestly, I am a little disappointed as the laptop feels too plasticky and the screen is also quite fragile with a lot of flax.

Software and Specifications: This is one area that this laptop shines brightly owing to it's potent combination of a high-powered chipset, RAM, and efficient GPU. The Asus R510J is powered by an Intel Core i7-4720HQ quad-core processor at 2.66Ghz, which can go up to 3.66GHz in turbo mode. Supporting the chipset is a dual-channel 8GB RAM, which helps in adept multi-tasking. Besides, the Nvidia GeForce GTX 950M with 2GB memory is old, but fairly decent to run most modern day games.

The Asus R510J offers high performance and can run all modern day gaming titles on medium/ high configuration depending on the game.
Apart from that, the laptop runs on a Windows 10 64-bit operating system out of the box, Wi-Fi, Bluetooth, and 1TB hard disk. There is no doubt that the specifications offered are pretty decent; however, I feel that Asus should have paid a little more attention to little things. For instance, the R510J doesn’t have Solid State Drive (SSD), which significantly hampers gaming prowess. Not only in case of running games, but the absence of SSD also considerably slows down loading time during running heavy apps.
