Choosing a portable Bluetooth speaker comes down to five things: power, battery life, size, water resistance, and price. Here is how to think about each one.

Power: What do watts actually mean?

Look for RMS watts, not peak watts. RMS measures sustained output — the volume you actually hear. Peak watts are a marketing number.

5-10W RMS: Good for personal listening, small rooms, desk use. Example: Stromberg Spark (10W, $29.99)

10-20W RMS: Fills a medium room or small outdoor gathering. Example: Stromberg Burst 2 (20W, $39.99)

30-40W RMS: House parties, larger outdoor spaces. Example: Stromberg Groove (30W, $99.99)

60-80W+ RMS: Large events, bass-heavy music, DJ use. Example: Stromberg Mega Force (80W, $199.99)

Battery life: Real numbers matter

Most brands test battery at 50% volume. At full volume, expect 40-60% of the advertised time. A speaker rated for 10 hours will last about 5-6 hours at max. Look for brands that specify their testing conditions.

Size and portability

Think about where you will use it most:

Pocket/clip-on: Under 8W, great for hiking, gym, commutes

Backpack-friendly: 10-20W, versatile for most situations

Boombox: 30W+, best for parties but heavier to carry

Water resistance: IPX ratings explained

IPX4: Splash resistant (rain, poolside)

IPX5: Handles water jets (shower, beach)

IPX7: Submersible up to 1 meter

Most portable speakers are IPX4 or IPX5. If you need full submersion, look specifically for IPX7.

Price: What you should expect

Under $30: Basic speakers, 5-10W, good for personal use

$30-$100: Best value range — solid power, good battery, useful features

$100-$200: Party speakers with serious output, EQ, mic inputs

$200+: Professional or audiophile territory

The right speaker depends on your use case, not the highest spec sheet. A 10W speaker with 10 hours of battery might be a better daily companion than an 80W speaker you only use at parties.
