Review on Talentcell Rechargeable 72W 100Wh 12V/8300mAh 9V/11000mAh 5V/20000mAh Battery Pack: Ideal Power Solution for LED Strip, CCTV Camera, and More! by Melvin Belton

I purchased this back up battery pack for use as an extended source for my Yaesu FT-60 handheld radio. Having the 9V & 5V options are a great feature! This means that while camping or hiking, I can charge up my cellphone as well as have additional power for my handheld radios. Although, for my purposes, I wouldn't use the 9V option, plenty of other electronics use 9V power sources. I would use the 12V & the 5V options. A great big thank you to Rome Jia for helping me through the process of getting & using this battery pack for devices.
