Don’t Get Stopped at the Gate: Keep Some Power in Your Pocket

There are many ways to miss a flight, but a dead cell phone shouldn’t be one of them.

Unfortunately, new TSA security regulations for some foreign airports require that cell phones and other electronic devices be turned on while going through security. Devices that cannot power on won’t be allowed on flights. This rule doesn’t currently affect domestic U.S. flights; just some incoming international flights from certain destinations.

One way to avoid such hassles is to travel with an external battery–one that connects with your phone or tablet via a standard USB cable. As long as you keep these portable power banks charged, you’ll always be able to give your device enough juice to power up and get through security. The good news is that many power banks are slim, stylish and inexpensive.

When shopping, keep an eye on a battery’s milliampere-hour (mAh) rating, which gives you an idea of which devices it can charge and how long it can keep them going. For example, Innvovative Technology estimates that its Justin-brand 2,000 mAh power banks provide enough power to add nine hours of talk and web surfing time to a smartphone and its 6,000 mAh units will increase smartphone time an extra 27 hours or add five hours of web, audio and video time to a tablet. For the sake of comparison, note that the internal battery of an Apple iPhone 5s is rated at 1,560 mAh.

Innovative Technology’s Justin Slim Power Bank barely makes an impression in a jacket pocket but has enough room inside for a 2,000 mAh battery. Four LEDs let you know how much of a charge it has left.

Moonstone power banks from Lepow (photo at top) are encased in smooth, polished plastic and come in an assortment of colors and power capacities. Moonstones comes in 3,000 mAh, 6,000 mAh and 9,000 mAh versions and provide two USB ports: one standard and one higher-powered, fast charge port. Thus you could charge a smartphone on one port and a tablet on the other. Moonstones are roughly three inches square but vary in thickness.

Also colorful and stylish are the Magicstick power banks from Powerocks USA. The purse-size small cylinders house a 2,800 mAh battery and come in a choice of eight colors.

The Champ Bodyguard Battery Rechargeable Power Bank adds a flashlight and a personal alarm siren to its capabilities as a 2,200 mAh lithium ion portable battery.

Some coffee shops and restaurants, like the ones in New York’s Madison Square Garden and a few Starbucks locations in Boston, now offer wireless charging hotspots built into some of their tables. Place a compatible smartphone or battery on the right spot and the device will charge up without wires.

The Duracell Powermat GoPower Overnighter charges smartphones and tablets with a standard USB cable, but the unit itself can be charged via an AC adapter or computer USB port or wirelessly by placing it on a Duracell or compatible wireless hotspot or charging station. The 4,400 mAh battery has a single USB port and comes precharged for immediate use.

Rayovac 2-Hour Power Pack

Rayovac’s inexpensive 2-Hour Power Pack doesn’t even need a USB cable. The small unit has a built-in micro USB port and plugs directly into your smartphone. Instead of a built in rechargeable battery, it uses a removable Rayovac CR123a battery, which you may be able to find at an airport electronics stores should your unit run down at the wrong time. A similar version with a connector for the iPhone 4S and earlier iPhones is also available.

Like the Lepow Moonstone, the Anker 2nd Gen Astro series chargers can charge two devices at the same time via two USB ports. Anker’s PowerIQ technology in the 2nd Gen Astro (6,000 mAh), Astro2 (9,000 mAh) and Astro3 (12,000 mAh) identifies the device connected to each intelligent USB port and adjusts the charging current accordingly.

Anker 2nd Gen Astro

The Anker 2nd Gen Astro series units lack buttons: To wake them up you simply shake them. A circular power readout lets you know how much of a charge is left inside.

Of course none of the above power banks will do you much good at the airport security gate or anywhere else unless you remember to charge them regularly. So power up and happy travels.

Swype for Windows 7 Debuts in New HP Slate 2 Tablet PC

The Swype technology that makes it possible to type without lifting your finger from your Android smartphone or tablet screen has cracked the Windows barrier and is included in the new Windows 7 powered HP Slate 2 Tablet PC.

A small, but significant logo sits at the bottom of the screen on the new Windows-powered HP Slate 2 Tablet PC announced today: Swype. Yes, the same Swype utility that lets you type by sliding your finger across your Android smartphone or tablet screen without lifting it has come to Windows 7.

The 1.5-pound Windows 7-powered HP Slate 2 Tablet PC (starts at $699) has an 8.9-inch capacitive multitouch display which supports both pen and finger input, a 1.5 GHz Intel Atom Z670 CPU and a preinstalled copy of Swype, which up until now had only been seen on Android, Windows Mobile and Symbian devices.

The unit is meant for business and will not be marketed as a consumer device, said Kyle Thornton, category manager for HP Emerging Products at a recent HP press preview in New York. It’s meant for retail and other business uses where full access to Windows applications is needed. It has an SD Card slot for storage in addition to an internal solid state drive and a 3-megapixel digital camera on the rear and a front-facing VGA webcam.

According to HP, the battery should last up to six hours on a charge and the unit offers a number of built-in security features, including a TPM (Trusted Platform Module) chip. A dock adds two USB 2.0 ports and a single HDMI port to the unit.

Business-friendly options include the HP Retail Mobile Point of Sale Case, which has a magnetic stripe reader and barcode scanner and the $79 HP Slate Bluetooth Keyboard and Case (above), which folds out to support the slate as if it were a notebook and closes up to protect both the keyboard and the HP Slate 2 Tablet PC.

Note that while Swype comes preinstalled on many Android devices, it can also be added to Android devices that didn’t ship with it. Swype Beta is available for download at no charge but does not work on all Android devices, especially those with older versions of Android or have relatively low-resolution displays. (Don’t install Swype Beta on a unit which came with Swype. It won’t work.) Swype is not available as an separate installable Windows application for other Windows tablets.

The HP Slate 2 Tablet PC will ship later this month and will be available from the HP website.
