If you’re on the hunt for an all-in-one charging solution with enough juice to power a laptop, then look no further than the Voltaic Generator Bag. This durable waterproof case is emblazoned with a 15-watt solar panel that can produce a peak output of 20 volts. A single hour of solar exposure will yield between 12 and 45 minutes of laptop runtime (depending on your computer), and the built-in battery pack will be fully charged after 5 hours in the sun.
The problem with portable solar chargers is that they need to be exposed to the sun in order to work – which makes generating electricity on-the-go a challenge. Enter the nPower PEG – a kinetic energy generator that harvests energy from your movements as you go from place to place. Simply drop the nPower PEG into a backpack or satchel and then go on a hike, a run, or ride your bike – the device will convert your energy into electricity that can be used to charge your cell phone, MP3 player, or camera.
Why settle for solar or wind power when you can have them both at the same time? That’s the idea behind the K3 Charge – a portable power source that taps the sun’s rays and the prevailing winds to give your gadgets a jolt of juice. Whether you’re off the beaten path or just hanging out in your backyard, it’s perfect for powering MP3 players, cameras, GPS units, or cell phones.
Powerfilm Rollable Solar Charger
If you’re looking for a flexible solution to generating renewable energy, the rollable Powerfilm Solar Array has you covered. This lightweight photovoltaic panel packs down to a compact parcel that can be unfurled at a whim to maximize solar exposure. A 5-watt, 5.4 volt array of monolithically integrated thin film panels provites the perfect amount of juice for charging practically any handheld gadget – from phones and game systems to cameras and MP3 players.
If you happen to be a bike-rider and you want to get the most clean energy for your buck then consider investing in a pedal-powered bicycle generator. This robust system harvests energy from pedaling your bicycle to generate a serious amount of wattage – you can produce enough energy to power a desktop computer, a mini microwave, a blender, or even a PA system!

the voltaic bag works great. i’ve had one for a couple of months now and i put it by the window of my office while i work. charges like a charm!
Does that power peg thing work by shaking it? the design is a bit perplexing.
i used one of those roll-away chargers during my time in the peace corp! the sunshine was definitely ample in mali, but it charged all my electronics!
i’m totally putting my husband to work on that bike generator. he could use a few lbs, and i would love nothing more than to watch television powered by his weight loss. awesome!
LOVE the nPower PEG idea. People forget that we’re walking energy sources and this product makes use of that! Well done, and great reporting!
I want the pedal bike in toddler size so my daughter can burn off some steam while revving up my laptop!
i haven’t had much luck with wind-charging devices. i bought the hymini and it didn’t work very well at all.
i wish there was a way of pumping the electricity you make on the bike into the grid, then just get free energy later
I’m bringing that K3 charger on my next camping trip!
what a great way to put my morning bike ride to good use! i’m going to get that bike generator!
the npower peg is one of the coolest ideas i’ve ever heard of
Swooning over the wind and solar charger. That thing is rad!
I love that nPower Peg charger! So useful and convenient. Definitely going on my wish list…
Great ideas here – I had no idea a bike charger could power a microwave.
I wonder about the durability of the rollable charger…
I like how the nPower Peg makes you work for your power – in a good way!
Great list Pete! Nice going. I totally want to check out the nPower Peg!
the pedal power bike is amazing!
The bicycle generator is on my wish list!
