Average Reviews:
(More customer reviews)This USB Battery Charger package (RAYPS19) is a poor value, becuase:
- The Rayovac PS19 USB charger is extremely primitive. It simply charges at a fixed current (200mA for AA, 90mA for AAA) FOREVER! The two green LED indicators do not go off when batteries are fully charged. It is up to the user to remove those batteries after a certain number of hours, depending on the estimated capacity of the cells.
- The two rechargeable batteries are the Rayovac 'Everyday-Use' AA cells. This is the cheapest NiMH cell offered by Rayovac. Its capacity is very low at just 1400-1500mAh.
If you are looking for a better USB charger package, I recommend the Sanyo eneloop USB Charger. It is available at similar cost, but offers the following advantages:
- The Sanyo MDU01S is a smart charger, meaning that it stops charging when each cell is full. Its charge time is much shorter, because the charging current is higher (850mA for one cell, 450mA each for two cells). Furthermore, it comes with a short USB cable to plug into your computer's USB port. This is much better than having a bulky USB charger sticking out from your computer.
- The Sanyo eneloop AA cells have a higher capacity of 2000mAh. More importantly, they are the low-self-discharge type. That makes them especially suitable for low-drain appliances such as wireless mouse, and also for high-drain appliances (such as digital cameras) that are used intermittently.
[Update on Aug 17, 2010]:
I noticed that the Amazon product image is incorrect. It shows a 4-cell Rayovac 'Easy Charger', PS131. Check my Customer Image to see the correct picture of this 2-cell USB charger, PS19.
