It almost seems like yesterday, but I remember a few months after I first purchased my E-10 in early 2001, being completely unaware of how digital cameras sucked the life out of Alkaline and NiMH batteries, did I come to know Maha and their PowerBank series. At the time, the MH-DPB140LI was available (released in 2000). Oh my how life changed for me and my image taking.
The latest PowerBank series, is the MH-DPB220LI. 2200mAh of pure Lithium Ion joy. It's been around for a few years, but since I just so happend to stumble upon a PowerBank back in 2001, I hope you've stumbled upon this review. It will change your image-taking experience.
Maha makes two versions of their PowerBank line: The NiMH (currently the 6V 1800mAh MH-DPB180M) and Li-Ion (currently the 7.2V 2200mAh MH-DPB220LI) version. Why the two different versions? Some digital cameras have a lower power tolerance, and the MH-DPB180M is more appropriate.
PowerBank units are a very cost-effective alternative to the many other forms of battery operated devices available. Not only can you use it for powering your digital camera, but you can use it for portable CD players, MP3 players, and basically anything that accepts the range of the PowerBank's voltage.
One of the most impressive benefits of the PowerBank is charging it for about 3 hours, and then storing it in your camera bag for later use. The PowerBank's design makes sure its charge does not easily dissipate. Maha says about 10% per month is lost during storage, but in my particular experience, I've had a PowerBank last around 18 months with 2 green LEDs still shining bright. Don't ask how this happened, but I was quite amazed. And impressed.
