drivergreg Posted February 24, 2015 Report Share Posted February 24, 2015 First time posting... I recently purchased the 7000NEX, and it has not arrived yet. Can I bench test this unit for power-up, using a "Battery Tender" trickle charger which is rated at 1.25 amps? Greg Quote Link to post Share on other sites
jhren Posted February 25, 2015 Report Share Posted February 25, 2015 I recommend against it... at least by itself. Most trickle chargers have switch-mode power supplies, some not very well filtered. Your typical 12V battery has no problem dealing with output ripple. May also have multi-stage voltage output. Simply put, trickle chargers are not designed to power electronics. Use a conventional 12V battery.... with or without the trickle charger ...or a bench-set 12V power supply. Quote Link to post Share on other sites
rockthebeef Posted February 25, 2015 Report Share Posted February 25, 2015 I don't have a spare 12V battery and I sold my 12V power supply a long time ago, thinking I'd never need it. I have ended up bench testing my head units by running a cigarette lighter plug to my car, which is parked right next to my bench, then running wires from that to alligator clips that I used to power the test units. I also used alligator clips to run the speaker outputs to some random 4ohm speakers I had in my garage. Worked for me, although I'll probably get another 12V power supply someday.

drivergreg Posted February 26, 2015 Author Report Share Posted February 26, 2015 Thanks... Scratching the trickle charger idea. Connecting straight to the battery won't be a problem. I didn't even think of using the cigarette socket. I also have a cig plug and bunch of alligator to alligator connections. Quote Link to post Share on other sites
rockthebeef Posted February 26, 2015 Report Share Posted February 26, 2015 You can also get a cheap power supply from a hobby store. These are much cheaper than other 12V powers sources made for CB radio, etc. http://www.hobbyking.com/hobbyking/store/__19680__HobbyKing_350w_25A_Power_Supply_100v_120v_USA_Warehouse_.html Edit: found this too https://www.google.com/shopping/product/810825727753794962?q=12v+cb+radio+power+supply&espv=2&biw=1184&bih=550&bav=on.2,or.r_cp.&bvm=bv.86956481,d.eXY&ion=1&tch=1&ech=1&psi=tlTvVIzaA8ihNuP4geAD.1424970934767.5&prds=paur:ClkAsKraX5NB07Zh1nedfkDNO2ARVqZk6pUPDFSZE2g6ubfXRIXraSwSX4gZMYA_c4v4bPiDQje6Mz8xbgkhn975I638te2zdkq_4FDm92VVw9yYFCi0v8hepBIZAFPVH73sn4pSmlcwrjndCEdtZOI_UUFgyQ&ei=vFTvVID0ItP3ggSKiYG4BQ&ved=0CLIBEKYrMAQ Quote Link to post Share on other sites
