Power Bank usually output at a Voltage of 5V with current up to 2.1A (MAX), however in some cases, when you want to charge a bit faster, increase the current will not help as most of the devices usually draw up to 1A (MAX). Hence, if you want to charge a bit faster and not afraid of damaging your devices, you can try to use the Hyper Charge approach.
Hyper Charge is just a random name for the technique that rise the voltage of the output USB port by 0.5V to 1V. Hence, the maximum power delivered to the devices will be increased from, for example 5W (5V 1A) to 6W (6V 1A). Hence, the devices should thermostatically charge a bit faster.
Power supply usually is a problem that occurs when you go camping or long period of outdoor activity. The time that this power bank was made, the common power bank volume you can find on the market has a maximum of 10000mAh. That is quite enough for daily uses but not for those who go camping every years. Hence, I made myself a giant power bank with solar charging system.
During camping, there is no electric plug for charging your power bank. Hence, I need to find an alternative sources of power supply which Solar power come into my mind. We all know that Li-ion Battery will lose its stored capacity during unused period. And the solar panel on top was to reduce the energy lose by continuously charging the Battery just to refill its energy lost.

Universal Charging Port (UCP) is a Standard USB Port that allow both Charging and Output of the Power Bank. If there is 12V Input to the Power bank via 2.1mm Power Jack, the UCP will output a 5V 3A (MAX) of power. If 5V 1A was applied to the UCP, the Power Bank will start charging itself.
Hologram on youtube or instructables are always a hot topic. You can buy those cheap Hologram stand for a few dollars, but actually, you can make your own.
Due to the over simple mechanism of this DIY project, I better just post pictures and let yourself to decide how to make it.

Side Views with our Old Logo
You can see the thin transparent screen makes a 45 degree angle with the bottom card board. Hence, when you place the mobile phone onto the screen, the light reflects from the screen and create a Hologram like image. You can also change the black background to other image just to look cool.
