ChessVolt Battery Pack review

Awesome product. I bought it to go with the Mil830 King Performance electronic chess set. No need to have the chess set close to a wall plug. No need for the wall plug cable dangling from the chess set to the wall. The ChessVolt battery pack makes it possible to play on the porch outside. Great product. ChessHouse is the best place for any of your chess needs. Best prices and best customer service. Walter

Perfect Supplement to the Millennium M820 Chess Computer

I use this as the only power source for the M820 as it allows playing anywhere inside or away from the house, no need to be near a wall outlet. It truly lasts for at least 8 hours of play before needing recharge. This is at the difficulty level I am using now of Normal - 0; using more computing power at higher levels may discharge it faster, I don't know, haven't tried this yet. I always leave the battery connected to the computer. When done with a playing session I turn off both the computer and the battery. I recharge with the computer and battery turned off, but still connected to each other. It took about 4 hours to fully charge after being about 2/3 discharged. I think this slower rate of charge probably prolongs battery life compared to fast-charging. The battery barely warms during charging. The M820 and battery were shipped together, and they arrived less than two days after ordering, in perfect condition, well-packaged. Shipping was free. -Bob Clem
