Input:
User Review: Nice idea, but there are some drawback. I did not purchase mine from Amazon. The first unit I got barely put out 1 watt from the small antenna. I sent it back to Midland under warranty, and they sent me a new one. The new one puts out 3 watts from the small antenna port (acceptable, but I wish it was 4 watts)

Pro: Nice small unit that can be used as a portable CB/Walkie-Talkie or in a vehicle with the mobile adapter which has an external power source (cigarette lighter) and external antenna connector.
When using an external antenna, this unit works as good as any other modern budget Chinese made CB radio with the same features. I do not think it is as good as the Japanese CB radios from the 1970's and 1980's.
The main unit (head) can be removed when used in a vehicle, so it doesn't get stolen.
It comes with two battery packs. One for use with regular (Alkaline; Lithium) batteries, and one for use with rechargeable batteries. The rechargeable battery pack will recharge the batteries with the enclosed AC adapter.
Has weather channels.

Cons: The small antenna and battery pack has very limited range, and is only good for use around a campsite. I doubt it will broadcast past 100 yards in wide open spaces with the small antenna.
The transmit button is next to the channel change buttons. Once in a while you may accidentally change channels when you think you are pushing the transmit button.
The mobile adapter has the coax and power cord wound in a coil. Winding a coax cable into a coil creates a choke which may alter SWR and power output. When you pull on the unit the wound coil changes shape, so the choke will also change. Cobra makes a similar unit that doesn't have a coiled section.
The rubber plug that covers the MIC and SPK ports breaks off easily. You will lose it eventually.
The cigarette lighter plug doesn't stay firmly in any of my GM trucks 3 lighter sockets. If you pull too much on the unit when you bring it to your mouth to talk, the plug sometimes comes out, and the unit shuts off. This is annoying.
