The JBL Partybox 310 is built for moving the party outdoors. With 240 watts driving the sound and an 18-hour battery, it can carry a backyard cookout, a tailgate or a beach day well past dark. You don't need an outlet nearby, which is the point of a speaker this size.

We'd consider this a strong fit if your routine involves playing loud music for a group away from the house. At $499.95, it comes in about 5 percent under the typical price over the last 90 days, so it's a reasonable moment to buy.

When this speaker makes sense and when to skip

An open patio, driveway or park space is where the Partybox 310 earns its keep. The battery takes power cables out of the equation, and the light show gives a dark yard something to watch. If your listening happens mostly in one living room, a stationary speaker with more inputs and no battery might serve you better for less money.

This is a large, heavy speaker, so think about where it will sit and how you'll move it before committing. It also won't replace a full PA for a band or a DJ set with many microphones; karaoke features are listed, but not the number or type of mic inputs. Check the connections you need and whether the app covers your phone before you check out.

From source to room

A battery-powered 240-watt speaker suits outdoor group listening, not a fixed living room setup.

Weigh the size and weight against how often you'll actually move it.

Confirm your mic, mixer or instrument connections and app compatibility before buying.
