I was rather surprised by the fact that these are not just premium branded batteries from China. They are in fact manufactured in Japan. They have excellent lives and are high recommended for most users. They also cost less than Energizer and Duracell. Good value for what you pay for.

8 pcs of Tenergy D Size 10,000mAh High Capacity High Rate NiMH Rechargeable Batteries Review

I was in market for a nice D sized rechargeable and got so disappointed by those in target/walmart that marks 2500mAh, looks like all that energizer/duracell did was put a bigger shell outside a AA battery and sell for much more money. I got 4 of these Tenergy cells from a friend, and they are simply AMAZING!

Not only the capacity is so huge, but also I heard they are the new generation low-self-discharge, and after a few months use, I can testify that all these are TRUE!

One bad thing for me is that I do not have a good charger, my old D cell capable charger can only do 500mA, so it took a whole day and night for me to charge them, but I have never had to do the recharge often at all, it lasts so long that I feel like it is battery than those disposable duracells, although I have not done any precise measurement.

I believe my last set of duracell disposable lasted about a month or so in the baby swing set, and the tenergy lasts for well over a month in my impression, coz I only had to charge them twice so far within 4 months.

I know my AA NiMHs will dry out in 2 months even if I do not touch them, so the low self discharge seems really helped.

Combining all the facts - 10Ah huge capacity, low discharge, and rechargeable! I am sure these batteries are the best D cells I've ever used!

Creative D100 Wireless Bluetooth Speaker (Black) Review

Creative D100 Wireless Bluetooth Speaker
Average Reviews:

(More customer reviews)
Given this is the first review, I will be thorough.

I've owned the Creative D100 Wireless Bluetooth Speaker for two months (paid $78.47).I'm very pleased.The sound quality is excellent for this type of speaker.The volume is loud enough to completely fill a room or a small outdoor area (e.g., patio).I've enjoyed it on the beach and found quality does not suffer much at high volumes.

Like with any small speaker, if you crank it to max volume, there is some distortion on bass-heavy songs.But the distortion is slight, and the bass sounds great if you have the volume appropriately set for the type of audio you are streaming.

On that note, there is no remote.The only way to control the volume is the `volume up' and `volume down' buttons on the front of the speaker or directly from streaming device ONLY IF it allows it.That is, my iPhone (3G - iOS 3.1.3) CANNOT change the speaker's volume while streaming, but my laptop can.In my use, I have not needed a remote.Usually I directly set the speaker's volume for the environment (e.g., bathroom, patio) and forget it.No remote also means you must control the streaming media from your device.There are no media control buttons on the speaker.

There is an auxiliary input on the back of the speaker, if you want to hook up a non-bluetooth device, or maybe just to save battery by not using Bluetooth.

Pairing with Bluetooth-capable devices (in my case, iPhone 3G and HP laptop) is simple and quick.

Battery life (four AA) is excellent.It is so long I cannot even put an estimate in terms of hours.It also came with an AC adapter, but I have never used it.The battery compartment is underneath the speaker.

The speaker is fairly small and very light.I actually carry it from room-to-room to enjoy while I am doing chores.

My only concern with the speaker is the build quality.The plastic casing is sturdy, but the front face of the speaker (surrounding the name plate and volume controls) is made of cloth.The cloth is spongy, but I am worried that it will inevitably tear with my heavy use of the speaker.There is no travel case included with the speaker.

Looking for a portable Bluetooth wireless speaker, I also considered the Logitech Z515 ($90, smaller and cloth-free).I've never used that Logitech speaker, but I ultimately chose the Creative D100 based on superior reviews for sound quality and bass quality.Look into both.There are good reviews for them and a comparison on CNET, if you want more information.

On the front of the speaker:
Volume up button
Volume down button
Bluetooth connect button

On the back of the speaker:
Power (on/off) switch
Aux input
5V AC adapter input

Underneath the speaker:
Battery compartment (four AA)

Tenergy T-1199B Universal Ni-MH & Ni-Cd Battery Charger With Timer Control Review

Tenergy T-1199B Universal Ni-MH & Ni-Cd Battery Charger With Timer Control
Average Reviews:

(More customer reviews)
This is one of those things where if you want something cheap that works well, and don't mind the size or old technology, it is OK.

To qualify that, it is 9" long, 3" thick, and 4" wide. That is a MONSTER for the features this thing has.

It should also be noted that this charger works on a timer circuit. With the switch set to "NiCd" it charges for 5 hours, and with it set to NiMH it charges for 8 hours. The charging is at a set rate, so that means in a given time, it can only put out so many mAh. (it varies by cell size, using different contacts at the center point of different sizes of cells)

Here's a quick example: If you have a AA rechargeable, and you set this charger to "NiMM" it will charge at 250 mA for 8 hours. That is a total charge of 2000 mAh. The problem is that modern AA rechargeables are rated 2400-2650 mAh. So this charger will not give a full charge. A 2650 mAh AA will only end up 76% charged, if it is fully discharged. You can start another charge cycle, but if you don't remember to pull the batteries out part-way into it, you will be overcharging them.

As a simple charger, it works. But battery technology marches on. Capacities get higher. My recommendation is to invest in a peak detecting charger.

I use a Multiplex LN5014, with a battery holder from Radio Shack. Of course that is a $75 charger, and requires a separate power supply. But I'm sure there are other options available in an inexpensive charger.

Sony ICF-CD815 AM/FM Stereo CD Clock Radio with Dual Alarm Review

Average Reviews:

(More customer reviews)
The old clock radio finally died and my husband and I thought it would be nice to have a CD player in the bedroom to listen to audio books in bed now and then (yes, I know, but it depends on the book!!).We've found the sound quality on such an inexpensive item to be extremely good, it's easy to tune the radio in and we like the huge time display - I can even see it without my glasses at night!!So far, it's awakened us at our ridiculously early get up time during the week without fail.No complaints - very happy with this clock/radio/CD player.
