"PedalCell is to your old bottle dynamo what SpaceX is to the Wright Brothers – they’re vaguely related, but one will take you much, much farther. Set-up is easy, intuitive, and took me five minutes the first time around, and maybe 1-2 minutes each time after that. The clamp comes with various size rubber adapters to ensure a perfect fit. Rough asphalt, bumpy gravel, poorly-negotiated jumps… the clamp never came loose.
Suffice it to say that the device offers a stable, fast, and very powerful charge, no matter the temperatures, and maybe more importantly, it does so even if you’re not fast… On each outing, my cell phone was running with the screen on and charged noticeably faster than with my riding buddy’s SON dynamo hub."
"Review: PedalCell dynamo outpowers hubs, works on any bike"
"PedalCell is a new take on a design nearly as old as the bicycle itself – the bottle dynamo, running on the front wheel. PedalCell has used the latest supercapacitor technology and a high-output dynamo to create a charging system that beats the pants off hub dynamos in terms of power overall and especially at low speeds.
The design is robust, looks good paired with racks and bags, and critically delivers a lot of power at lower speeds more associated with long-distance riding. Price-wise per watt delivered, it beats out any dynamo hub/USB charger combination, without the special skills or tools that building charging into a wheel requires. It comes with a two-year warranty too."
"Review: PedalCell bicycle power source"
"PedalCell offers significantly more power than any other USB charging system, it’s 42-70% more power than the best hub dynamo charging setup tested (Schmidt SON28 dynamo hub & Forumslader V5 charger). PedalCell has been tested to be more efficient (68%) than the best dynamo hub and the Velogical works out to be only a touch more efficient (35%) than a lower-performing hub.
There is a very strong case for the PedalCell if, like me, you travel at speeds averaging between 8 and 20KPH. The drag is low and the power output is high at these speeds – there is simply no hub dynamo setup that gets close at low speeds. Everything in the PedalCell charging system, in particular, has been optimised to work together – from the rim dynamo through to the charging circuitry."
