    Awesome Deal for OEM Droid Charger, September 15, 2010

    I purchased these from Bargain Cell for my Droid X. They are identical in every way including output ratings of 5.1v === 850mA. The part number for the cable is SKN5004A while the charger’s is SPN5504A. These are exactly the same as what came in my Droid X box.

    As any Droid X owner knows, the Droid X gulps battery power and you can’t have enough chargers. I also happen to have a thermoplastic polyurethane (TPU) case for my DX. Unfortunately, the thicker cable ports on my long micro USB cables do not insert flush inside the micro USB port of my DX. However, the Motorola OEM cable ends are very thin and therefore plug in more easily and stay plugged in. This is why I only sought out chargers and cables that were Motorola OEM.

    Keep in mind that the cable is short. This works well when charging from a counter top location but terrible if you’re running the charger from the ground to the top of a desk. In that case, you can always use USB extension cables, which is what I’m doing with one of the 4 chargers I have. Lastly, Bargain Cell shipped the charger quickly and I received it on the same day as a charger I ordered at the same time from Amazon using 2-day shipping.

    Charging times using the Motorola SPN5504 Battery Charger, April 19, 2011

    This review is from: Motorola SPN5504/SKN5004A micro-USB Home and Travel Charger (Wireless Phone Accessory)

    For those interested…

    The output rating of the Motorola SPN5504 Battery Charger (as of April 2011, no longer directly stocked by Motorola) is 850 MA (milliamperes) at 5.1 volts. The lithium-ion battery within the Motorola Droid 2 Global cellphone, Type BP6X, is rated at 1420 mAH (milliampere-hours, typical). So, if you were to use the cellphone, discharging it down to the 5 percent level (as indicated on the “Battery Management” screen of the cellphone), the time it would take to recharge the phone to 100 percent (fully charged state) would nominally be 95 minutes, calculated as follows:

    Recharge time = (Percent_discharged x Battery_capacity) / battery_charger rate, i.e., (0.95 x 1420) / 850 = 1.587 hours or 95 minutes.

    Similarly, charging rates for given percent battery discharges are:

    90% – 90 minutes
    80% – 80 minutes
    70% – 70 minutes
    60% – 60 minutes
    50% – 50 minutes

    The above are “nominal” charging times. If the battery has a different capacity or the battery charger has a different rating, then the charge times will differ accordingly. If the battery charger cannot provide 850 milliamperes output (i.e., the nominal rating is less than 850 ma – as may be the case with a “cheap” battery charger), then it will lake commensurately longer for the battery to be fully charged. (For example, if the battery charger has an output of only 650 ma, the time to fully charge the 1420 mAH battery in the cellphone from a 95% discharged state would be 124 minutes – significantly longer.)

    I actually tested the above, using my almost new (3 weeks old) Motorola Droid 2 Global phone with the OEM Motorola battery BP6X (provided with the cellphone) and the accompanying OEM Motorola Battery Charger SPN5328B (marked output rating: 850 mAH at 5.1 volts). The cellphone was discharged to the 5% point, at which time the Battery Charger was connected to the phone. The actual charge time to reach the 100% fully charged state was 94 minutes.

    Hope this helps!

    Genuine Motorola Charger – Real Quality Power, October 27, 2010

    This is an excellent USB charger, which delivers up to 950mAh power to your sensitive devices (In my case, a Motorola Droid 2). I have searched around the internet and have found a lot of issues people are experiencing with cheap chargers, especially newer smartphones. There are mixed results, but it seems that a “quality” charger is the safe way to go, as the generic chargers (including the cell phone company branded ones) can deliver “dirty” power. By dirty I mean it isn’t a continuous flow of amps, with spikes or harmonic distortions. On most phones that have been made, this isn’t a problem because the power is just filling the battery. But, with newer devices, they may experience malfunctions, and even damage/destroy your phone!

    I was prompted to buy another one of these chargers because my OEM one that came with the phone was used in my bedroom, and I was using a generic USB charger in the living room which was giving me difficulty. Whenever I plugged my phone into it, I could hear an ultra-high frequency whine/hissing noise coming from the charger, and my phone’s touchscreen would malfunction! Screen taps would be accurate about 80% of the time, with some of them being totally erratic. Unplugging the phone from the generic charger made this behavior go away… and I never tried it again. I received this charger, hooked it up, and have not had any hissing or abnormal screen taps since. I’ll never hook my Droid 2 into a non-Motorola charger again after hearing some people’s stories of destroying their Droid/HTC Incredibles. If you own a smartphone, this is the charger for you.

    Almost perfect, May 2, 2008
    This review is from: Sunbeam Health at Home Standard Moist/Dry Heating Pad (Health and Beauty)

    My wife and I have been using this product for a variety of things and it has been great. When you turn it on, it doesn’t take long to heat up which is great. At its highest temperature, the heat setting is just right, hot enough to bring relief without becoming too hot or uncomfortable. The only thing we wish was different is that once it has been on High for a while, it begins to cool down and does not become hot again until its cooled down first. This is a little frustrating if you wanted it to be hot for longer. We have tried turning it off and unplugging it at that stage, waiting a minute or two and then plugging it in again and having it on High but this doesn’t seem to make it any faster. It still doesn’t reach High again until its cooled down first. Other than that, its wonderful and has been a huge help for sore backs, necks, and other ailments. 🙂

    NOT what I ordered!, March 2, 2009

    This review is from: Sunbeam Health at Home Standard Moist/Dry Heating Pad (Health and Beauty)

    I have 3 major complaints about this product. First, the picture of the heating pad I THOUGHT I ordered was not the one that arrived. So if anyone else is interested in this particular heating pad — BEWARE!!! That ISN’T the one you’re going to get! Amazon.com obviously has the wrong picture listed for this item. Second, the medium setting on this heating pad isn’t nearly as warm as the medium setting on my old one so I have to turn this one up to the highest setting in order to get the same amount of heat. Third, once it gets hot (on the highest setting), it then starts to cool down. After it (cools down) a little bit, it heats back up again. After a few minutes, it begins to cool down again and so on. This cycle of heating/cooling is continuous the entire time it’s on the hottest setting. I suppose it must be some sort of a safety precaution because it doesn’t have an automatic shut-off feature but it’s VERY annoying. Nowhere in the Amazon.com description does it mention this feature nor is it even mentioned in the instructions that come with the product itself. As far as heating pads go, this one is okay, I guess. But I was disappointed when I didn’t get the one I thought I was ordering.

    This product exceeds my expectations. I use it for upper back pain, lower back pain, and neck spasms. The 3-position heat control is very useful. My only complaint is that the unit bunches up inside the removable/washable cover and you have to straighten it out every so often but that is easily accomplished.
