I'm getting intermittent blinking red light. Sarts a minute in when hooked up. Is this broken?

Mine would do that , also. Just wait until the light is a steady Green. You should be fine. It should all be in the instruction papers. Remember this is a trickle charger and it takes awhile. Good luck.

Could this be powered by a DC power bank for 1-2 weeks? What size would be needed?

No, this product requires 110V AC power input and outputs 12V or 6V DC power. It has a trickle charging function, allowing you to keep your battery charged without damaging it or your device.

what is its acceptable range of input ac voltage? (i know it centers around 120)

Hello, Michael Forrest The specifications of this charger are as follows: Input:100-240V~2A 47-63Hz; Output:12V=-= 2A 6V=-= 0.6A. It is designed to be compatible with all 6V and 12V lead-acid batteries, including the following types: Pb, GEL, SLA, VRLA, and AGM lead-acid batteries.

Can this charge a dead 12 volt battery? I have a dead battery for my camper that needs charged, then maintained until spring.

It can if the battery is in otherwise good condition. I had a battery that it would not charge and I had to replace and I found out a couple of the sales inside had collapsed and therefore it would not take a charge, so it depends on the condition of the dead battery.
