A traveler who carries a charging station in a backpack doesn’t run out of gadget or laptop power

2016-09-10

When you are traveling – perhaps exploring a new city and snapping photos on a camera, using your smartphone for navigation and reading notes and tips from a tablet – it feels like it is always the wrong moment when the battery dies on one of the devices (that’s why we carry two cameras with us). If you are carrying your stuff in a backpack, why not have a backpack that can charge your gadgets on the go? It is a fine idea that we really like to try out when the HP Powerup Backpack becomes available in mid-September.

The product concept is that HP has designed a backpack that can be used as a charging station while you are on the move. Throw in your gadgets, books, water bottles and snacks and go. When the power runs out from your smartphone, laptop, tablet, ereader or camera, plug it in to a USB connector in the backpack. The built-in power bank charges your gadget. Note: you may charge your camera only if it has the same power input as a smartphone or a tablet.

The thing with this backpack is that it has enough power to charge a big 17-inch laptop, or a smartphone up to 10 times. That’s a lot of power (22400mAh), but it also means that from time to time, you have remember to recharge the backpack (or rather, the power pack inside it).

The backpack that doubles as a charging station is priced $200, for instance, at Amazon.com. Would it be possible to build a similar backpack for less money? Most likely, but keeping the charging process cool enough and avoiding water are challenges that must be solved in any case.

Ereaders, Tablets and Smartphones Are Adopting Solar Power

2015-03-05

Ereader devices that come with greyscale E ink displays are so energy-efficient that they can go without recharge for weeks. If you are trekking in wilderness or staying in a remote village without electricity, you can still read ebooks on an ereader. Tablets and smartphones, however, need a recharge after a couple of days of moderate use. Solar energy would be the obvious solution for charging our mobile devices even in remote areas, but affordable solutions have been missing until now.

Two new solar energy solutions have been introduced recently: Bboxx solar panel and Wysips Crystal display technology for mobile devices.

Bboxx solar panel is a product package that includes two panels and a USB hub. The solar panels can stand on the ground where they catch sun rays. The USB hub is connected to the panels, and mobile devices can charge their batteries simply by plugging in to the hub.

Worldreader organization that provides ebooks and reading devices to regions with low literacy rate has adopted Bboxx system as their solar power solution for ereaders.

Wysips Crystal display technology that can be used in ereaders, tablets and smartphones has been developed by SunPartner. In this solution, the solar charging capability is built in to the display. The technology adds a transparent layer into a display that catches solar rays, and converts them into electricity that charges the device battery.

Ereader manufacturer Bookeen and electronics company Kyocera have announced that they are going to use Wysips Crystal displays in their future products. Bookeen will create an ereader that can charge itself via its own display (in 2016) and Kyocera has demonstrated a smartphone that can charge itself from light.

Here is a video where Kyocera’s solar-powered smartphone is demonstrated.
