ChargeMate is a small connector you must have for your USB cable.

It has multiple features:

  • Voltage/current meter for monitoring charge states

ChargeMate is a meter measures the charging voltage and current in real time and displays the values on a small but clear OLED screen. You could use these information to know your charge states, check if a charger is a good one, or find out which cable provides best charging speed.

  • 2X fast charge when connecting to PC

ChargeMate has 2 modes, one is the normal mode which passes through the USB 3.0 data lines, thus enables a normal charge/sync cable. The other is the intelligent charge mode, which provides the optimized fast charging solution, while the data sync function is disabled so your data is kept secure.

When connecting your phone/tablet to PC, you could select the intelligent charge mode to shorten the charge time. That is because PC normally uses half power for the data communication whenever your phone is connected to it via USB cable, by disabling the data communication, the full power could be used to charge your phone.

  • Intelligent charge with most chargers

Different phone/tablet has different charge requirement, such as iPhone, Samsung tablet, BlackBerry, etc. When you connect it to different chargers, such as wall charger, car charger, power bank, etc, some of them just does not charge or just charge with limited current less than 500mA. With ChargeMate, you can always be sure to get the most optimized charge current to charge your gadgets.

  • Auto power off to protect your battery

When you charge your phone for a long time especially during night, the charge power is still connected to your phone once your phone is fully charged. Although most phones have the feature to prevent your battery from being over charged, it will keep your phone at the full charge state all the time, which will reduce the battery capacity and shorten the battery life.

With ChargeMate, once your battery is fully charged, it will automatically power off the cable, just as you unplug the cable from your phone, thus to protect your battery.

  • Multiple charge protections to keep your gadgets safe

ChargeMate provides the following protections:

  * Over Voltage Project (OVP)  

  * Under Voltage Protection (UVP)

  * Over Current Protection (OCP)

  * Under Current Protection (UCP, Auto Power Off feature)

  * More protections may be added later

  • OTG support to share power, connect USB storage, joystick, etc.

Nowadays, most Android phones/tablets support OTG feature. OTG is the abbreviation of On The Go, which means your Android phone could act as a USB host to provide power to other gadgets, connect USB storage, mouse, keyboard, joystick, camera, printer, etc.

ChargeMate provides an OTG Micro USB header which could be pulled out from the normal USB A male header, connect it to your Android phone, then connect other devices to the USB A female header of the ChargeMate, you are on the go. For example, with your OTG supported Android phone and CharteMate, you could rent power to iPhone, or directly play movie saved in an external USB storage.

Timeline

Why KickStarter?

Just as the above videos show, we have finished the prototype of ChargeMate, now we need the funds to make it a real product. With your support, we are sure we could bring ChargeMate to life. 

Risks and challenges

The prototype of ChargeMate is already functional. We had successfully fulfilled our previous electronic U-DICE campaign on schedule, we are confident in this campaign as well. That to be said, there is always the possibility of delays due to things beyond our control at the manufacturer’s facility. We will keep you closely updated with the progress and work hard to deliver your ChargeMate on schedule.
