Better than OEM
on September 28, 2012
I am impressed with the product and the value. The "off-brand" Bower batteries are actually rated at 1800 mAh in comparison to the 1240 mAh rating of the Sony branded battery. That is nearly 50% higher capacity. Does the charge last longer? My experience is that the charge lasts significantly longer. The charger itself is certainly not "of lower quality" as another post here suggests. I'm not sure what charger it is being compared to as so far, no one has seen a Sony charger for this battery. It charges from "empty" to full charge in about 1-1/2 hours. It also comes with an adapter for your car's power outlets and a European-style receptacle adapter. I have not tried either, but will see how well the charger works in a car. Being able to charge a spare battery in a car is a huge plus for people on the move. This same charger can be purchased for as little as $4.75 elsewhere by itself, and the batteries at $8.80. That compares favorably with the price of the kit here. The Sony brand batteries are list priced at $49.95 although you can get them for as little as around $32 on line. But that is still nearly four times as much for a battery that has less capacity. Yes, they are Chinese manufactured just as the DSC-RX100 is, and just as the OEM battery is.
If is certainly possible that the OEM battery has a longer useful life, but the Bower battery has a 5-year guaranty. If the battery lasts 1/5 that long in daily use I will be happy--after all, they are a consumable. The camera itself has a 1-year guaranty and it is not "consumable."
In summary, no one should avoid these products because they do not carry the Sony brand. They are well built and represent a solid value. I will not be buying a Sony battery at four times the price when I can obtain a product that is certainly worth more than 1/4 the price of OEM batteries.
