There are small UPS (uninterruptible power supply) that run on internal batteries for a sufficient period to enable a safe run-down of your PJ. They switch in (as the name suggests) immediately, uninterrupted. You would need to check locally for a price. You can also buy BIG ups that would run the whole house, obviously these cost a lot more.

I've just been to check and here in the UK you could buy an UPS that would run a 360Watt load for 20 minutes, this would reduce as the UPS gets older but it should be good for 3-5 years without a problem. My JVC PJ runs at 280watts so i would imagine yours would be similar. The cost of the UPS I looked at in the UK would be around £50.
