Three options that I know of: AA cell phone charger (which you're already using) -- uses 2 or 4 AA's to recharge your gadgets. I use an Energizer model to charge my GPS for rides over 12 hours. Of course you need to carry enough batteries for the length of your ride. Solar charger -- can be mounted on a handlebar bag, a rear rack or hanging from your ...

I have a HTC Hero which I charge using one of Ladyada's Minty Boosts (v2), when it gets caught short. This uses 2 AA batteries (which could very well be pre-charged rechargeables) to charge the phone (2 AAs give me between 20% and 30% of a full charge in about 30 minutes). I don't tend to charge using it while I'm riding, as it gets rather hot, and I'm not ...

You might look at just upgrading your current approach—a lithium battery based cell phone charger (like the popular New Trent ones) generally go a lot further than AA based ones.

Probably the easiest way to fix your problem is to reduce the amount of power the GPS on your phone is using. By default, most GPS tracking programs eat up an enormous amount of battery because they default to maximum-accuracy settings. However, if you're going on long enough bike rides that you are worrying about battery life, you can probably afford to ...

There is this company that sells bike powered phone charger kits. The price is very reasonable. I think this one may be suitable for your HTC because my husband has an HTC Incredible. http://www.bike2power.com/smartphone-bicycle-charger-kit.html. Not sure if they would ship to UK. I got the kit for his b-day because he also complained about the battery ...

Staying lit while totally stopped, for example at a junction, is a function of the light. It's definitely worthwhile, and a modern LED dynamo light with standlight function will give reasonable light for quite a while when stopped. Theft of dynamo lights seems to be rare, but if you are worried, consider using non-standard screws or bolts to make it harder ...

There's a project on Kick Starter that looks like exactly what you're looking for: The Siva Cycle Atom The funding ends May 23rd 2013, and they should start shipping towards the end of 2013. So if you miss the window to be a Kick Starter backer, you should be able to pick one up directly form them around then.

On my commuter bike, my front dynamo hub charges a small 18650 battery that I then can tap to provide power to my smart phone. You need to have an intermediary battery because most dynamos only produce the German government mandated 6VAC / 3 watts minimum, which is around 0.5 amps (500 milliamps) -- and this is only when you're going faster than 15 km/h. ...

Most front wheel motors will work on the trike and will install in a very similar way. There are a lot of kits on ebay, ranging in price from a couple of hundred dollars up through sensible prices to quite silly. See this question for some opinions on the cheap kits. Most crank motors will also work and be easy enough to install. This Sunstar kit, for ...

I called the shop where the dynamo was bought, and let me explain how to connect a cable. My summary: Unplug the plastic cover from the correct socket: One is for ground, one for phase. Thread the dismantled tip through one of the two holes in the cover. The length of the dismantled tip should be so that part of it protrudes below. Bend the protruding ...

I use a small external rechargeable USB backup battery. When the runtastic app & GPS run the phone battery down after 3-4 hours I connect the external battery for a few hours and it keeps the app going plus recharges the phone battery. I keep both the phone and backup battery in a small pouch on the top tube so I can hear the app say "distance, 24 ...
