Power on Board (450 Amp battery to jump start or charge cell phones/Black berry). This unit also contains a small air compressor. Small bag contains Volt meter, 120 volt charger and tire pressure gauge. The jump start charger part of this unit works very well but the air compressor is too slow to pump up my TV or PUP tires.

I plan to populate ths gallery with stuff I've bought that turned out to be a duds. Of course I'll show the alternatives that were effective.

He Ruide > Tongue wheel chock - If you have chocked the tires you don't need this. Plus it prevents you from moving the trailer while hitching up and if you bump the trailer with your TV it could damage your tongue jack

He Ruide > Lynx blocks (or a piece of wood) are a better alternative if you are on soft ground and there is risk that the tongue jack wheel could sink into the ground.

He Ruide > I saw this on a trailer at the storage area that I store my PUP. It brought a smile to my face as I thought this was definitely grounds for divorce!

He Ruide > I do not recommend this type of analog meter. You really need a meter that can read 2 decimal points to monitor battery status. This type of analog meter is not accurate enough.

He Ruide > Any of these multimeters will meet the need for basic trouble shooting and checking on the battery status.

He Ruide > Q-MAXX MF1052 - 12 volt High volume air (2.54CFM) compressor. It comes with a 16' hose, 8' power cord and case (Not shown). This is a better air compressor to pump up tires.

He Ruide > I tried using a wireless remote camera to either hitch up to my PUP or to see while backing up. I never had good reception and prefer to use the hitch balls to hitch up or getting up frequently while backing up my PUP.
