How we ranked these guitar amps
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- Power weight 3
- Speaker size weight 2
- Built-in effects / amp models weight 2

Buying advice: portable guitar amplifier
Match watts to the playing situation
Watts set how much clean output an amp gives before it starts to break up, so compare the wattage figures first. The JOYO gives 15 watts, while the Spark MINI and the Vox AC MINI each give 10 watts. A higher wattage figure suits players who want more headroom, while a lower figure suits practice at home. Check the wattage row in the spec table before choosing between these three.
Count effects, models and practice tools
Built-in effects and amp models decide how many sounds you get without extra pedals. The Spark MINI offers 30 amps and 40 effects, and the JOYO offers 9 preamp models with modulation, delay and reverb. The JOYO adds a looper, 36 drum patterns and a footswitch, while the Spark MINI adds Smart Jam backing tracks and a smart app. The Vox AC MINI gives an analog circuit, spring reverb and a boost switch.
Check battery, weight and what is included
Battery life and weight decide how easy an amp is to move between rooms. The Spark MINI gives up to 8 hours of battery at 3.8 lb, and the JOYO gives 8 to 12 hours at 9.8 lb. The JOYO box includes a footswitch, cables and a power adapter, while the Spark MINI works as a USB audio interface for recording. Compare the weight and battery rows before choosing an amp to move between rooms.
