Review on Super Power Supply® Raspberry External by Dustin Wright

Update (03/09/2015): I overclocked my original Raspberry Pi to 950 and the unit runs stable with this power supply. However, I bought a second one and it doesn't work. Charging my Galaxy S4 but powering the Pi. I deduct a star for that. (Three to two.) First rating: This is a good power bank that works well for charging my 2013 Nexus 7, Galaxy S4 and HTC One. However, I bought it to run an overclocked Raspberry Pi with Raspbmc and it doesn't seem consistent enough for that. I haven't tested the voltage, but using the settings at the bottom of this review (which have been proven to work on other Pis with good power supplies) will cause the Pi to reboot under heavy load. CPU load. Settings: arm_freq=1100core_freq=550x264_freq=275isp_freq=1v3d_freq=275sdram_freq=600over_voltage_sdram=4over_voltage=8disable_pvt=1initial_turbo=60hdmi_ignore_cec=1force_turbo=1
