Sorry, I posted this thread in the wrong section in the beginning of the week. Hey everyone. I've been out of the hobby for more than a year now and miss a lot the hobby but the prices for these pinball machines are too high, so even if I would love to come back, I'm out for good now. Anyhow, I want to install a GPS on my 5 Mopeds (my new inexpensive hobby) and I'm not sure which one of these 2 step up power supplies I should go for, the moped has a 6 volt battery and I need 12 volts output for the GPS but do I need 2 amps or 4 amps? https://www.ebay.com/itm/DC-5V-11V-To-12V4A-48W-Step-Up-Power-Supply-Converter-Regulator-Module/192350866803?_trkparms=aid=111001&algo=REC.SEED&ao=1&asc=20160908105057&meid=14ba2c4fb9b747668226f1caeda926a6&pid=100675&rk=1&rkt=15&sd=192350866803&itm=192350866803&_trksid=p2481888.c100675.m4236&_trkparms=pageci:c0cd34c6-2e17-11e9- bb86-74dbd18032b6|parentrq:dd544b281680aa492278e4d9fffed37d|iid:1 https://www.ebay.com/itm/DC-5V-11V-To-12V2A-24W-Step-Up-Power-Supply-Converter-Regulator-Module-New/192431747204?_trkparms=aid=111001&algo=REC.SEED&ao=1&asc=20160908105057&meid=14ba2c4fb9b747668226f1caeda926a6&pid=100675&rk=2&rkt=15&sd=192350866803&itm=192431747204&_trksid=p2481888.c100675.m4236&_trkparms=pageci:c0cd34c6-2e17-11e9-bb86-74dbd18032b6|parentrq:dd544b281680aa492278e4d9fffed37d|iid:1 Your input/experience would be greatly appreciated. I would've posted this on the "other" Montreal Forum since I'm in Quebec but they blocked me from getting access to my account for no valid reason about a year ago. Thanks. Claude.
