| I looked at the one you bought and it's less than 70 watts continuous, | (5 amp x 13.8V = 69 watts) so, IMHO, it wouldn't have enough juice to | run, say, a Triton charger at more than about half rate.
Of course, if you don't get into the larger electrics, you'll probably never need to feed your Triton more than 5 amps. And even if you do get into the larger electrics, the Triton limits LiPo charging to 2.5 amps for some strange reason, so even then you probably won't need more than five amps.
And even if you do get some big 24 cell NiCd pack that can be charged at 5 amps, you can still charge it with your power supply and a Triton
-- just charge it at 1.9 amps or so. It'll take longer, but it should work fine.
So don't sweat it that your power supply doesn't match what your charger might use --

It should be OK with any charger. Just keep the charge rates down well below 5 amps if your battery pack needs more than 12 volts, and below 5 amps if the battery pack needs less than 12 volts. And if all you fly are park fliers, it'll probably never be an issue.
