Says reduced from £100 to £50. Decent sound from a portable radio. Has built in Li-ion battery, which has better life than AAs, and not an added extra like the pure chargepaks. Also charges while plugged in, rather than having batteries that have to be taken out to be charged. Has bluetooth function for streaming your phone or tablet thru. Lastly will also charge Devices which charge via a USB outlet on the back of it - i.e. like a power bank. Seems decent for the money to me.
