should i buy Storacell by Powerpax Slim Line reviews

AS easy to use as 1-2-3. Press on the bottom of the battery with your thumb to breach the locking tab, continue pushing the battery in the center opening, then twist out and pull battery out. No more Loose Batteries! Unique locking feature holds batteries firmly in place. Torison bars allow more flexibility and longer life of locking feature. These powerpax are great battery holders that are simple, lightweight, and fuctional. They are constructed from a rugged polymer and are priced fairly. In addition, They are made in the USA and used by various branches of the military to power their two way radios and other electronic devices.

If you have a lot of electronics, chances are you are going to need batteries. If those electronics are portable and you carry them when you go out, then you need to have some sort of storage for them. Without proper storage, the batteries may be damaged from coming into contact with one another. These powerpax ensures they are safe while on the go.

You simply slide the battery into each slot; you will feel them lock into place, indicating that the battery is fully into its slot. You can put them in plus side up or down and get adequate production both ways. There is a little tooth on the top of each slot that locks each battery firmly in place and limits movement will in the caddy. Theere is almost no movement at all while in the case. However, they are also very easy to get up by simply pushing up and sliding the battery out.

Many battery cases sold on amazon and in stores have quality and function issues. These items just work and work extremely well. They are great for camping, camera bags, or just to stay organized around the house. powerpax caddys are great productions that I highly recommend. Not much to say that others haven't. In summary: they load and unload individual cells easily (and one-handed), they hold them tight, and there is no latch or hinge to break like on other plastic battery holders. This is in my EDC to hold AAA eneloops for my various flashlights, headlamps, walkie-talkies and other device which may use this cell size.

Four, instead of five, stars for seeming expensive for what is essentially a piece of plastic, even if it is a very nice piece of plastic.

I am a photographer and let me tell you, having batteries loose flying all around is never any fun. I mostly carry Eneloop rechargables in AA and AAA sizes and it can get really annoying. This thing is so great at holding them, haven't ever seen any come loose or spill out. It does great and helps me organize my camera bag.

Four, instead of five, stars for seeming expensive for what is essentially a piece of plastic, even if it is a very nice piece of plastic. Most of the battery caddy industry seems fixated on multiples of 4 and rarely has designs specifically for AAA batteries. Powerpax fills market needs with a wide range of products of sturdy and durable products.

It looks like the battery caddy has two kinds of clips, a vertical and a sideways clip. On the AAA caddies I received, with sideways clip, the batteries aren't coming out without a fight. I find it a bit hard to open the clip enough to get the batteries in an out without damaging/peeling the battery's shrink wrap or whatever the plastic film that is wrapped around the battery is called. And it tends to separate my thumbnail from my thumb, trying to pry the clips open enough to get the batteries out.

It think this is more of a problem with the smaller AAA caddies. The clip tension is overkill for AAA's. The caddies larger batteries are probably fine. I use to tape batteries together and put them in bags with the tool they were needed for now, I have purchased Slim Line Battery Caddies for AAA, AA, and 123A's and it has made organization and storage so much more easy and convenient. The AAA caddy holds 6 batteries and they maintain good retention while they are in motion, I keep them in my EDC, and Buschcraft pack and have yet to find a stray battery floating around.

should i buy Duracell Mobile Charger reviews

Duracell Mobile Charger with 2AA and 2AAA Pre-Charged (CEF23DX4) essentially serves as a portable power hub, delivering power from 4 charged batteries to a variety of high drain ranging from digital cameras to Blackberries to MP3 players

The Duracell Mobile Charger (CEF23) is an extremely versatile charger. It actually has two operating modes, as selected by the MODE button:

1. As an AA/AAA NiMH battery charger, or
2. As an USB charger for USB-powered devices.

In battery-charger mode, the unit is a smart charger that accepts 1-4 AA/AAA cells in any combinations. The charger can be powered by either 100-240V universal AC input, or 12V DC input. This means you can also operate it from your vehicle's cigarette lighter adapter. Note that the car adapter is included in the CEF23DX4N, but not in the CEF23DX2.

The charging current is 550mA for each AA/AAA cell. So it takes about 4 hours to full charge up the included 2000mAh low-self-discharge cells (which are the Duracell-equivalent of Sanyo eneloop). I consider this a good compromise between shorter charging time and longer battery lifespan. Once charging is done, the current is reduced to 25mA (actually 0-50mA pulsed at 50% duty cycle) in trickle charge mode.

One really nice feature of this charger is that it has four individual battery status indicator lights. The status light for each cell turns RED when charging, GREEN when the cell is fully charged. It will even blink if you accidentally inserted an alkaline cell.

In USB charger mode, the unit generates a regulated 5-volt supply at its USB socket. You can then connect an USB-powered device (such as IPOD charger) to this unit. Input power for this USB charger can be from one of the following sources:
1. From 100-240V universal AC input,
2. From 12V DC input (car adapter), or
3. From four AA/AAA NiMH cells in the battery compartment.

The third way is the most interesting, because in case of emergency, you can even use 4 alkaline cells to power this USB charger, in order to charge up your cell phone's battery.

I must say that this charger is really well designed. It is a great bargain even if all you need is a simple battery charger. The USB charger mode is just an extra bonus.

[Update on Oct 7, 2010]:
Duracell has discontinued the excellent CEF23 charger (at least in the US) last year. So prices for the remaining inventory have skyrocketed. The replacement product (Duracell Go Mobile Charger) only charges in pairs, and does not contain an USB charger.
- If you just need an inexpensive 2-cell charger that can handle individual cell, consider the Sanyo eneloop MDR02.
- If you need a good 4-cell charger that can operate from 12V cigarette lighter adapter, consider the Targus LCD2700 with LCD Display
- If you need an advanced charger that can operate from 12V CLA, consider the La Crosse Technology BC500
- If you need a good 4-cell charger that can operate from 12V CLA _and_ can power an USB port using internal batteries... Sorry! Your best hope is to look for an international version of CEF23, such as the CEF23AU (AU=Australia)

[Update on Dec 1, 2010]
Just in case anyone is still interested in this charger: I recently found out that its USB port is capable of supplying 1000mA output current - even though the spec says 500mA only. I discovered this by accident when using it as a portable recharger for my Archos 5 500 GB Internet Tablet.

I've done a lot of research on batteries and chargers, and I have to say I'm impressed with this charger. I am a photographer, and my fancy flashes are only as good as the batteries they use. Other reviews have already stated the high points: gentle charge rate (550 mA is great); individual charging of batteries (absolutely vital); intelligent shutoff (does not overcharge). On top of these, it runs off of 12V and any AC wall power in the world (120-240V), and it charges USB devices. It also will charge a USB device off of 4 charged batteries. It's a dream come true.

One thing to note: You cannot charge batteries AND charge a USB device at the same time. You have to pick one or the other. But this is a very minor issue for something so functional, portable, and inexpensive.

Assuming it doesn't die in two months, this is the best consumer charger that is widely available. (I also have the Maha C-9000, which I love, but is not for the faint of heart. The Maha C401FS is also very good.)

If you're even considering buying one of those 15-minute chargers, PLEASE don't. It will destroy your batteries by cooking them at a high temperature. Buy this one, instead. Just get an extra set of batteries to swap out while the others are charging, if you need the quick turnaround.

First, a note on what's included: 2AA, 2AAA, a charger, and a car adaptor. It does not come with a usb cable. You can see the customer photos I uploaded.

As noted by others, these batteries are "highly similar" if not identical to Eneloops. So the batteries are great.

For AA, I like the charger included in this kit more than the one in this Eneloop kit for two reasons:

1. Each slot has its own individual indicator so you know which battery is done. Equally importantly, you can detect bad batteries in a set. Say you always use four as a set but one suddenly finishes charging a lot earlier than the other three, it's time for testing. (For testing, I use Maha MH-C9000.)

2. It charges faster, at 550mA, so the 2000mAh AA batteries charge in about four hours.

Unfortunately 500mA is also how it charges AAA batteries. Contrast this to the Eneloop charger in the kit above: 300mA for AA and 160mA for AAA. We see that the Eneloop charger is a lot more gentle for AAA. (I won't charge my AAA in this Duracell charger.)

should i buy Duracell Rechargeables StayCharged AA Batteries reviews

he name of this product has been changed to Duracell Rechargeables StayCharged AA Batteries. As far as I can tell, those are the same batteries previously marketed as 'Pre-Charged'. In other parts of the world, those are also marketed as 'Active Charge'. They are stlll available in either 'white top' (made in Japan) and 'black top' (made in China) versions.

- Amazon has combined the AA and AAA versions of those Duracell batteries into the same product page. So now I look like a fool who says the same things twice. Oh well...

[Previous update on Dec 24, 2008]
I was only half-right when I boldly proclaimed that "Duracell Pre Charged AA are rebranded Sanyo eneloop cells" in my original review. It turns out that the first batch of Duracell AA cells I bought from Amazon are made in Japan, and those are identical to eneloop (both mechanically and electrically). But lately I bought some more Duracell AA from a warehouse club. Those are made in China, and they are identical to the Rayovac Hybrid.

[Original review follows]

Judging from similarity of technical specifications and physical shapes of (+) and (-) terminals, I am convinced that the Duracell Pre Charged AA is actually SANYO eneloop AA underneath a different wrapper. Therefore all the good things you heard about eneloop apply to Duracell 'Pre Charged', too.

My own testing has shown that the capacity of eneloop AA cell is slightly above the claimed 2000mAh, and it is able to retain at least 85% of its charge after 5 months in storage. The Rayovac Hybrid AA starts with slightly higher capacity at 2100mAh, but it 'only' retains 80% capacity after 5 months. For all practical applications, both are equally good. Just pick whichever brand (Sanyo, Rayovac, or Duracell) is on-sale, and you can't go wrong.

One small problem with the Duracell 'Pre Charged' cell is that: it looked too similar to the well-known 'Copper Top' alkaline cell. So there is a good chance that people may mistaken it for a disposable cell. Personally, I prefer the distinctive-looking white case of the eneloop cell. Nice product, nice price, the batteries have more duration than my old batteries...i have two charges and the duration are the same. These are 800 Milli-amp hr batteries. If I had known, I would have bought locally. The price seems cheaper but they are the low grade batteries so you are not saving any money. Produce arrived quickly. Use to power Bose headphones and battery power source works as promised. Have not recharged batteries as yet but anticipate no problems. I always buy Duracell, they last really long time. Rechargeables are particularly good for house phones. The order was shipped promptly and on time. I received the newer 2450mah batteries, so the performance has been great.
I've had them in my Microsoft Mobile Mouse 6000 for a month and they are still working. well is just a battery,,, a really good one. need to say more?
(well for the sake of this review i will)I love these batteries so much that we are no longer using disposable batteries. They are great for the environment and easy on the wallet! I use these batteries for a laser pointer, as a toy for my cat! I shine the light around for her to chase (like a bug!) and have used it for hours per day. Before I bought the duracell, I went through batteries like crazy but these batteries are truly long lasting. You won't be disappointedThey've been on my arctic mouse since day i received them and haven't died just yet, there definitely better then regular batteries!
