10-watt combos are not considered mini-amps I think. Mini-amps are usually 5W or less and capable of battery power. In a sense, Vox Amplugs are mini-amps too. The idea is to be able to bring the amp anywhere. A 10-watt practice amp will still need a power supply.
Standard Value / SV Guitars has a mini-amp by a Korean company called Sound Drive. Perhaps that could be considered, too?
