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.

Buying advice: rechargeable guitar amplifier
Match watts and inputs to your setup
Watts and input count decide what an amp can run at once. The BP40D pairs 80 watts with 6 inputs, the Crush20 pairs 20 watts with two channels, and the 15-watt amp pairs 15 watts with two inputs. Count the instruments and microphones you plug in at the same time, then pick an amp with at least that many inputs. A two-input amp suits a guitar-and-microphone setup, while more inputs suit players who plug in several instruments at once.
Compare battery hours before you buy
Battery hours decide how long an amp runs away from a wall outlet. The BP40D runs 6 to 8 hours after a 5-hour charge, the Crush20 runs up to 8 hours, and the 15-watt amp runs 4 to 8 hours. Check the charge time as well as the playtime, since a longer charge means more waiting between sessions. Pick the playtime that covers your session length, among the amps that also give you the inputs you need.
Check outputs for practice and recording
Outputs decide how an amp fits practice and recording. The BP40D has a headphone output and a DI output, and the 15-watt amp has a DI-OUT jack plus a 3.5mm PHONES port that mutes the speaker. The 15-watt amp also has a 3.5mm port for direct phone internal-recording and live-streaming. If you practice with headphones, look for a headphone port. If you send audio to a mixer or an external speaker, look for a DI output.
