CaseDuo Charge & Sync Dock + 2nd Battery Cradle for Samsung Galaxy SIII - Black

Charge your Samsung Galaxy SIII AND a spare battery at the same time with this Charge and Sync Dock for Samsung Galaxy SIII from Monoprice!

This charge/sync dock is designed specifically to fit the new Samsung Galaxy SIII phone. A small plastic insert allows the dock to be used with or without an external protective case installed on the phone. A slot on the back side of the dock allows you to charge a battery directly, without the phone. This slot will fit both the stock Samsung 2100mAh battery as well as our 2100mAh Replacement Battery.

The dock connects to a PC, Mac, or USB power source through a USB micro-B port on the back. It measures approximately 3.6" wide by 2.1" high by 3.1" deep.

Great docking station

Pros: Great fit, appearance

Cons: none

I've tried the products from several merchants, and none of them worked.
This one works and, in addition, looks and fits great.

Doesn't Last Long

Pros: Good fit, adequate 1A power supply included.

Cons: Intermittent connection to phone over time.

Worked great the first few months, 6 months in it began to have connection issues. Now 9 months later it rarely makes a good connection with my SIII Galaxy. Disappointing given that I only use it once a day. The power supply is still going strong at least, just the jack at the back of the cradle is problematic. This is where the power supply connects to the cradle.

Works great.....but

Pros: Compact size
Ability to charge phone and backup battery

Cons: Will not charge with Monoprice's dotDefender PC+Silicone Case for Galaxy SIII - Black still on the phone.

Works as advertised. A "naked" S3 charges without a problem, as does the extra battery. Have had zero problems with it so far. However, I have the dotDefender PC+Silicone Case for Galaxy SIII - Black from Monoprice that I really like - but the phone and case together won't fit in the charge deck. I have to take the case off every time I want to charge my phone with the Charge Deck.

Works well!

Pros: Definitely made for the S3 Galaxy phone.
Comes with its own power supply, freeing up old one to go to work, in kitchen, etc.
Power supply connects to dock with the same USB connector as the phone itself, so other devices could be charged if necessary, or when S3 dies it can still be useful.

Cons: Battery charger slot is rather tight, so must be at proper angle to insert.
It would have been nice to have the "battery charged" light on the side of the dock, instead of the back. You have to turn it around to see the LED status.

I bought this model for the battery charger component, as my phone's connector/charging circuit has issues. Very good fit for my S3, with or without a case on phone. The removable insert is easy to take out for allowing encased phones to dock. Ordering a second one for myself today, as my wife took my dock for her S3 (in her words, "Now I don't have to find the cable to plug in with, and the phone is upright so I can read it from bed.")
