Can using chargers without their “bricks” (plugging directly into a USB port) hurt the device or just slow the charging?

I’m traveling out of the country (from USA to EU) and bought a couple converters for my electronic devices (tablet, phone, etc). My question is, can I leave the charging “bricks” with the standard plug at home and use the USB outlets on my converter to charge my devices or will that harm them. I think all it could potentially do is slow the charging on the ones that increase the wattage, but am I missing something? Thanks in advance!

It certainly can’t hurt anything, but it could feasibly be slower if the USB port has a lower amperage than the plug.

USB ports provide 5V DC, which is what your device expects. The “brick” part is just there to convert the wall juice (110-240V AC, depending on where you are, also the frequency might be different) to 5V DC.
