This looks like a promising, fairly lightweight and inexpensive ($50) way to recharge devices in the field. Its specs say it can run a GPS or cell phone, even if their own batteries are dead. Wonder if it would recharge camera batteries?

Energi To Go® SP1000 Powers and Charges Cell and Smart Phones, iPod® and MP3 Players and Bluetooth® Via Sunlight, Indoor Light or AC Power

Features Power Capacity: 1000 mAh @5V
Charge Time: 6 Hours Solar/3 Hours AC adapter
Built in LED flashlight
Pocket Size, Weighs 5.4 oz Dimensions: 4.5 (L) x 2.9 (W) x 0.63 (H) Inches
MSRP: $49.99
Package Includes: AC Adapter, travel bag and six cell phone tips

There's a slightly heavier, more powerful version for $100.

With the 1 a/h spec and 6 hr solar charge time, I suspect most users would be frustrated at the relatively low performance. It certainly will work but a lot of consumers will not have the patience to wait for it to work to full capacity. That may not be important if it gives you enough to do whatever needs to be done at the time. In that regard it may be used mostly to put a partial charge on devices so things work 'right now'.

I suspect you're right presidio, most people will expect it to work like a wall plug. :eusa_doh:

For me, it would be ideal to attach one to the lid of my backpack and recharge a camera battery while I'm hiking. The extent to which it powers anything else is a bonus. My current backcountry charger is about a pound and can provide 4-5 battery charges before it is depleted. Very helpful on longer treks -- especially when proprietary batteries are so expensive.

Looks to be several different models;  scroll down the page a little farther.

I hate to sound pessimistic, but I can't say anything with the 'Energizer' label lately has been crap.  Take for example their Ni-Mh batteries.  After about 10 charges, they fail to hold a charge more than about 3 days.

Not sure which Chinese subcontractor is making these solar chargers, hopefully not the same subcontractor that made the NiMh cells.

Assuming the camera battery is the same voltage as a GPS or cell phone it should work if you have the right cable.

Al

PS If the solar cells have more voltage than the battery, juice will flow from the solar charger to the battery. Amperage is important too and a function of time.

 Although we are steering off the topic, I say it is still we are with in bounds of the subject.

 The link provided by Professor SABill,is an excellent link to a prototype backpack-generator of energy. Bulky as it is shown, &nbsp;it provides a great inspiration for inventors to veer in the right direction of what the market is evolving in interest.Bottom line: Recycle and Energy Efficiency .

 Al, provided an excellent hint as to what we have seen at least on the big screen that can inspire great inventors to reach something worthy of approximating to fantasy and yet real enough to be a palpable goal.


Maud'Dib says, "check it out." &nbsp;I can't help but wonder about the efficiency of energy conversion.

 If we ever are lucky enought to get to see something similar to the Fremen Stillsuit ...(please scroll down the link).


 I think all our summer desert problems, would be resolved. And along with that many of the outside workers issues as well.

This is the part I find most intriguing.

Oh yeah, this is the best thing since sliced bread. You won't even need a generator for your camper if you get one of these. I bought two so I can power my house  :rolling:; one for all the lights and the other for the refrigerator.

Call it what you want, but the physics of solar charger efficiencies absolutely will disappoint a lot of folks who are expecting something that produces real power.

Market hype does not change the facts of usage. If you understand that and can work within the considerable limitations, then it will perform nicely. However, most consumers have little experience with solar charging and thus will be disappointed in the seeming lack of performance.
