Do you have the specs for the barrel connector?  I am partial
to Delta Electronics(*) brand switching power supplies, and I
tend to use the ADP-10SB Rev H for my common 5V 2A needs
(it does not hurt that a local surplus store had (at one time) dozens
available NIB surplus units at a very low cost (~$6 if I remember
correctly), so I picked up a few for immediate use, a few as spares
just in case (never needed as spares, since none have yet failed
me, but I have used the spares for new devices (I replace most POS
bricks supplied with consumer devices proactively)).  A quick online
check shows a few sources:

(be aware some offshore suppliers may not source the real thing,
and there are some other variants (non rev H) that have different
form factors or power connectors.  The rev H uses the standard
C13, and (I think) rev F uses a mickey mouse C7, and (I think)
rev B is direct plug-in for NEMA 1; choose wisely/carefully (and
remember other than the rev B, you have to provide/purchase the
power cord)).

As with all else, your specific experience will vary.

(*) There are many good suppliers of power supplies/bricks/warts,
and every supplier has bad samples/designs, but Delta Electronics
has a long history of being in the top tier for their own branded
devices (they will also build to order/price for some OEMs, which
may have better/worse components), so I have mostly stuck
with them (sometimes I will pick up a TDK-Lambda supply if they
are available/appropriate for my needs).
