While this review is for the HTC Droid Incredible version, the charger itself will work with any battery provided you purchase the tray for it. So, if you have multiple phones, you only need to buy the charger once.
The charger itself comes in 3 parts. From left to right – wall charger (included), HTC battery tray (included), HTC Touch Pro 2 OEM battery (for review purposes), and universal USB cable (included, bottom).
When fully assembled, the charger can charge both a battery and a phone at the same time.
Not pictured, but on the side there is a toggle for AC Power and USB power. The device will charge a battery off either, but can only charge two devices simultaneously off AC.
The inclusion of the USB cord seems almost pointless to me. For one, since the charger has a USB port, you can just use your phone’s included USB cord to charge it here. Also, the cord has 2 contacts shorted, so it can’t be used as a backup cable for connecting to a PC for data purposes. It will only charge. The benefit of this is a quicker charge off AC. However, the cable feels flimsy, and I’ve heard it tends to fail within a few weeks. Definitely not necessary for this product.
Otherwise, the charger does as advertised. It charges a battery and your device at the same time. Since I keep two batteries, I keep one in the charger, and one int he phone, and just swap out as needed. Thanks to this device, I haven’t had to plug my phone in to anything for the sake of charging. Forum Discussion.
You can purchase this charger for around $25 from Amazon.
