Pages: 1 mtw4518 member Reged: 09/12/12 Power source question       #5631352 - 01/19/13 11:13 AM Edit   Reply   Quote Quick Reply   I was going to buy a larger power tank to run my scope and dew zapper, but after reading all the comments on here about using a jump starter, I will go that direction. My only concern is the DC outlets on the power tank are fused at 10 amps, but all the jump staters I have found are 15 amp. Is this something to be concerned about?

As long as it is 12V dc output, you should be fine. Art Post Extras:       Midnight Dan Postmaster Reged: 01/23/08 Loc: Hilton, NY, Yellow Zone (Bortl...

The fuse is so the equipment attatched doesnt overdraw power? Post Extras:       Midnight Dan Postmaster Reged: 01/23/08 Loc: Hilton, NY, Yellow Zone (Bortl... Re: Power source question [Re: mtw4518]       #5632188 - 01/19/13 08:33 PM Edit   Reply   Quote Quick Reply   Correct. The equipment only draws the current that it needs. A power supply cannot "send" more. And yes, the fuse is there to protect the power supply, not the equipment that it is connected to. If the equipment were to develop a short circuit, it could start drawing hundreds of amps and, in the worst scenario, the battery could explode. The fuse prevents this from happening. -Dan Post Extras:       mtw4518 member Reged: 09/12/12 Re: Power source question [Re: Midnight Dan]       #5632206 - 01/19/13 08:58 PM Edit   Reply   Quote Quick Reply   Thanks I understand now, it makes perfect sense Post Extras:       Pages: 1
