Topeak Morph. Pick a flavor with the features you like. There are at least 6 different models with a variety of features. The switch from Presta to Schrader and back isn’t as simple as some floor pumps. It does require a bit of disassembly but it’s not difficult.

A pump that will work on tires isn’t going to work on a shock. The shock needs high pressure but very tiny volumes. The tires need low pressure but massive volumes. The tiny volume can be pumped easily even at high pressure. The high volume is much more difficult to get to high pressures. Most tire pumps also don’t have a pressure bleed valve on them. You need that to tune the pressure on the shock. But you only want to release a tiny amount of air because you only have a tiny amount if air in the shock.

The blow offs caused by gas station compressors probably had less to do with volume and more to do with the poor interface between the tire and the wheel. I always have to check small wheels on kids bikes when using a compressor at the co-op. The steel wheels on those bikes don’t use a good hook bead and will often slide off when filled from the hose. The speed of the air rushing into the tube seems too fast for the tire to react and it slips off the bead.

We do occasionally see a better quality bike with better aluminum wheels in small sizes. Those seldom have a problem. It could be a coefficient of friction problems as well.
