Review on Rechargeable 12V 3000MAh Lithium Battery Pack: Power Bank For LED Strip, CCTV Camera & More by Mood Neboet

I bought the power cell because the little QRP radio I bought an Ebay did not have an internal battery. It has a place inside the case to install one but may not have had one due to airline shipping rules that prohibit Lithium Ion batteries on aircraft. Not sure on this. The radio is designed to hold one inside though. But I bought this and plugged the power cable into the back and can run it on the external battery (this one) for several hours. The radio puts out about 3 watts or so on the HF ham bands. It's held up quite well at this point and the y cable that comes with it plugs right into the socket on the back. Same size jack. The radio is a uSDX HF Transciever. It's a very small low powered software defined piece of amateur gear.
