Most modern cell phone chargers (especially ones that put out >5W) are
small regulated switching power supplies in a wall-wart form factor.
It should be fine for that purpose, however if you're into analog you may
have problems with noise on the 5V line.

If it's a switching supply it will often (but not always) have a universal
input range (eg. 85-250VAC) and will be quite light compared to typical
wall-warts supplied with cheap prouducts.
