PS3 console. The DualShock 3 can be identified by its "DualShock 3" and "Sixaxis" markings. It also weighs , 40% more than its predecessor, the Sixaxis, which weighed only . The rear markings indicate the original DualShock 3 draws up to 300 mA of current at 3.7 V for a power consumption of 1.11 W, an order of magnitude increase from the 30 mA of current at 3.7 V (0.111 W) listed on the Sixaxis. However, this current is not drawn constantly and is the maximum current when the rumble is active. Its main power source is an internal 3.7 V Li-ion battery tentatively capable of storing 570 mAh, which provides up to 30 hours of continuous gaming on a full charge. Third party replacement batteries are also available. Like the Sixaxis, the DualShock 3 comes with instructions on how to remove and replace the battery. The DualShock 3 can also draw power over a USB cable via a USB mini-B connector on the top of the controller. This allows the controller to be used when the battery is low and is also used for charging the battery. When connected via USB, the controller communicates with the console through the USB cable, rather than Bluetooth. Along with the release of the 'slim' model PS3, Sony released a new version of the DualShock 3 (A1) which uses 5.0 V at 500 mA while connected, but still contains a 3.7 V battery. This revision of the DualShock 3 does away with the additional plastic brackets between the L1/R1 buttons and the L2/R2 triggers (increasing controller rigidity), has indicator lights soldered directly to the board, and comes in slightly revised color schemes. While the DualShock 3 is compatible with any standard USB mini-B cable and many USB chargers, official charging cables are available from Sony. These include an official cable, the USB 2.0 Cable Pack and a wall charger, the AC adapter charging kit. Any third-party USB charger used must act as a USB host device, rather than simply providing power over the appropriate pins, since both the Sixaxis and DualShock 3 require a host signal to "wake up" and begin charging. A Sony representative confirmed on April 2, 2008, that the original Sixaxis controller would officially be discontinued with the release of the haptic-feedback enabled DualShock 3 in mid-April 2008. The Sixaxis was no longer produced after 2008, being dropped from stock
