The PC5 is a Powerful Solar Charger That Can Both Charge and Actually Run at the Same Time iPod, iPhone, Droid, Blackberry, Palm, eReaders, and Other Devices Direct from Solar Energy Review

Average Reviews:

(More customer reviews)I've been doing a lot of offshore sailing lately and decided that I needed to find a way to keep my smart phone, ipod, and kindle charged up while away from 110 power. I had a cigarette lighter type charger for my phone, but nothing that would work for the others. Since I'd be outside and in the sun a lot, I figured solar was the way to go but wasn't sure that I'd be able to find something that would work for all three devices.
I spent a lot of time looking around online and saw plenty of chargers. Most of them were actually chargers with batteries - the solar cells charge a battery, and the phone, ipod, whatever charges off of that battery. Charging a battery to charge my device seemed like having an unecessary "middleman" to me, so I kept looking. Then I found the Suntactics PC5. This solar charger charges directly via USB - no middleman battery. I had a trip coming up the first of October, so I figured I'd take a chance and try it out. I purchased my PC5 charger in September, 2010.
I used the PC5 on that and a subsequent trip covering almost all of October and November - It worked flawlessly. It actually seems to charge my Droid X at about the same rate as my AC charger, and my ipod faster than the battery operated speaker I use at home). It works great for charging my kindle too. I just open the PC5 up, set it in the sun and connect whatever I need to charge.
While heading out east for one trip, I was stuck at O'Hare airport for a few hours and couldn't find a free outlet near my gate, so I just took a seat near the window and charged in the sun. Every time I set it up I got comments and questions about the rig.
The charger works great, is compact and easy to carry/store and it's "green". What more could you ask for? I couldn't be happier with mine.

Powerful Solar Charger for iPod, iPhone, Droid, Blackberry, Palm and most all small electronic gadgets including GPSs, eReaders, and portable gaming devices. It even charges the iPad in good sunny weather. This is not an ordinary small solar charger. These use high efficiency solar cells like the ones used in industrial grade solar systems. The solar cells in the PC5 charger really pack a punch!See if any other small solar charger can match the same solar energy output in such a small package.Other solar chargers use a small solar panel to trickle charge an internal battery, which takes forever! Their solar panels are too weak charge your device directly. So they charge your device from an internal battery instead. When the internal battery fails(which it inevitably will, since it's being baked in the sun constantly), you have to throw the whole thing away. The PC5 solar charger will not only charge your device, it will run it directly from the sun.And it will last for years. Use the PC5 solar charger to charge your handhelds while camping, on picnics, at the beach, by the pool, or ball games.Use it to solar charge your devices when there is no other power available. Take it hiking with you to charge that GPS device Use it for emergency power and disaster power relief. Most of the time cell phones still work when there is no electricity.Be the only one with a fully charged phone! No power no problem.Loose your wall charger? Why not start charging from solar?

Duracell Pre Charged Rechargeable Nimh AA Batteries, 6-pack Review

Average Reviews:

(More customer reviews)Now in 6-pack.
Regular NiMh batteries are old school; these new batteries are greener and better.
Pros:
-For a rechargeable battery, these batteries does not need to be charged before you use it for the first time
-They last a long time.
-Does not need special charger. You can use your existing NiMh charger.
Cons:
-Looks almost the same as regular Duracell alkalines except for the added color of lime green. You can confuse them with regular Duracells and mistakenly disposed away after losing charge.
-This later technology is still expensive. But you can get it on sale from time to time.
I also like Eneloops by Sanyo. But they are not easily available at your local stores unlike Duracells.
Duracells are made in Japan if it has a white top (around the positive anode) and made in China if it is black.

Duracell DC2400 - Battery 4 x AAA NiMH Review

Average Reviews:

(More customer reviews)OK. So notice most of the complaints are about the shipping time not the quality of the product.
Ordered 3/26 received in two days with prime.
As others have mentioned these are 900mAh batteries.
Ran the 4 cells through a few charge-discharge cycles on a BC-900 charger (also a good product available here). All of the batteries tested above 900mAh. 902, 926, 928, and 937mAh. This is with only a few cycles on them so it might creep up later but should not be much.
This is better performance than less expensive brands (ultralast, etc.) Those seem to test at only about 50% of the cells above the stated capacity, although they are often at least 85% of listed capacity.
Just my experience, with a small sample size. Choose which is best for you.
Would be 5 stars but could be a bit less expensive. Only a minor complaint.
Update 8/2/06
Used these in a GPS unit and MP3 Player mainly. Probably have been recharged around 10x each. Retested now they are at 900, 924, 930, and 932. so not much change

Rayovac Rechargeable NiMH Batteries, AA-size, 8-count Carded Pack Review

Average Reviews:

(More customer reviews)The latest family of Rayovac rechargeable NiMH batteries are all missing one thing: the capacity rating. Previously, you can see the charge capacity (such as '2500mAh') marked on every package and also on each cell. But newer Rayovac rechargeable NiMH cells are just grouped into three classes ('Everyday-Use', 'High-Energy' and 'Hybrid'), with vague claims such as 'Up to 275 photos' printed on their packages.
Of course, those claims make very little sense to us, because Rayovac never tell us which camera was used, and under what test conditions were those photos taken.
After a lot of searching, I was able to find the spec sheet for those cells from rayovacindustrial dot com:
- NM715-4OP 'Everyday-Use' AA, 'Up to 275 photos': capacity=1400mAh
- NM715-4B 'High-Energy' AA, 'Up to 375 photos': capacity=1900mAh
- LD715-4A 'Hybrid' AA, 'Up to 400 photos': capacity=2100mAh
The item offered here is the NM715-8OP (the 'OP' stands for 'Opening Product'). It has the LOWEST capacity amoung all Rayovac NiMH batteries. I have tested some in my La Crosse BC-900 Battery Charger, and the average capacity is actually higher than spec at 1500mAh. But this number is still very low by today's standard for NiMH AA cells. So although the price looks attractive, this is just not a good value.
As of this writing, this 8-pack (NM715-8OP) is actually priced higher than two 4-pack (NM715-4OP). Furthermore, the Rayovac 4.0 AA 4-PACK is available at even lower cost. Those are low-self-discharge cells with higher capacity of 2100mAh. So it is a no-brainer which package you should buy.
[Update on July 16, 2010]
I recently discovered a hidden benefit of those Rayovac 'Opening Product' AA cells: they are exactly the same size as alkaline AA cells, while other NiMH cells with capacity 2000mAh or over are all slightly thicker. So for some appliances with extremely tight battery compartment (such as the Rayovac Sportsman Xtreme 1W LED Flashlight), those are the only rechargeable cells I can use.
[Update Sep 4, 2010]
As if the offerings above is not confusing enough, Rayovac has now discontinued the 'Hybrid' series, and replaced it with another two types:
- LD715-4OP 'Pre-Charged': capacity=1400mAh
- PL715-4 'Platinum Pre-Charged': capacity=2100mAh

Rayovac Hybrid - Battery 4 x AAA NiMH Review

Average Reviews:

(More customer reviews)These are the best AA & AAA batteries I've ever bought. The mfg's claims that they hold on to a charge longer are basically true... far longer. The other "higher capacity" batteries I've used haven't given me as much usage between charges as these Hybrid types, so I am very satisfied.
What would have made them perfect is if I could have bought a smart charger (the kind that can charge in 4 hrs and handle single cells, not just pairs) bundled with them.

Rayovac Hybrid rechargeable batteries come pre-charged and ready to use. This battery technology also takes NiMH rechargeables to a new level. While all batteries self-discharge over time, Rayovac Hybrid NiMH batteries hold their charge better than many traditional NiMH batteries, while not in use. This means that customers can now charge their batteries and know that when they need them, Hybrid batteries will be ready to go without having to go into the charger again. Lasting longer in high-drain devices than regular alkaline, and being able to recharge over and over again mean convenience and value to your customers!
