How to read a karaoke speaker spec sheet, estimate real battery runtime, choose the right wireless microphones and test a sample before you commit to a container.
The wattage on the box is the most abused number in the category. Three different figures circulate, and they are not interchangeable:
Ask the supplier for RMS output, total harmonic distortion at that power, the supply voltage used for the test and the speaker impedance. A trolley speaker described as 100W should come with a clear statement of which kind of watt that is. Our karaoke range spans about 60W to 150W+ depending on chassis size, and a quote should state the power basis.
| Tier | Typical use | Common features | Buyer note |
|---|---|---|---|
| Compact, about 60W | Home, small gatherings, street vending | Smaller drivers, lighter weight, battery models | Easier to ship and a good first SKU |
| Mid, about 80 to 100W | Family parties, events, small venues | 8 to 10 inch driver, two microphones, LED effects | The most common container mix |
| High, 100W+ and up to 150W+ | Large rooms, outdoor events, hospitality | Larger cabinets, wheels and telescopic handle | Heavier freight and higher unit cost |
Battery claims are easy to inflate. A speaker rated for high power rarely draws its rated power in normal use, so runtime depends on the average load at the volume customers actually use. A simple estimate:
Runtime (hours) is roughly battery energy in watt-hours multiplied by efficiency, divided by average power draw in watts. For example, a 100 Wh battery at 85 percent efficiency and a 15 W average load runs about 5.7 hours.
Battery energy in watt-hours equals voltage multiplied by capacity in amp-hours. Ask for both, plus the cell type and brand, and the test condition behind any runtime claim (volume level, microphone use, lighting on or off). LED lights can use a meaningful share of the power.
The battery chemistry also affects weight, price and shipping. Lithium packs are lighter and charge faster, while older sealed lead-acid packs are heavier and cheaper but add significant freight weight. Lithium models need battery transport documents, covered in our shipping guide.
Most trolley karaoke speakers include one or two wireless microphones, normally UHF. The practical points for a buyer:
Because the microphones transmit radio signals, they need their own compliance evidence in addition to the speaker. See our certification guide for how radio and battery reports fit together.
| Feature | Why buyers care | Notes |
|---|---|---|
| Bluetooth | Phone streaming is the main source for most users | Check pairing speed and range |
| AUX, USB and TF card | Playback without a phone | Confirm supported file formats and maximum card size |
| Microphone and guitar inputs | Wired mic or instrument use | Look for separate volume knobs |
| Echo and reverb controls | Core karaoke effect | Knobs are more user-friendly than menu buttons |
| Recording function | Popular for social media use | Confirm how recordings are stored |
| LED lighting modes | Party appeal | Make sure lights can be switched off to save battery |
| Display or remote control | Convenience | Remote batteries and language of display should be specified |
A trolley karaoke speaker is a heavy product that gets dragged over curbs and stairs. Inspect:
Sign off the specification and a golden sample before production, and use a pre-shipment inspection with an agreed AQL, as described in our inspection guide. For regional preferences on power and features, see the karaoke export guide.
RMS is the continuous output under defined conditions and is the useful number. PMPO is a marketing figure with no standard method, so it can be far higher than real output.
It depends on battery energy and average load. Estimate with watt-hours multiplied by efficiency, divided by average watts, and ask the supplier for the test conditions behind its claim.
Most models include one or two UHF microphones. Two is popular in many markets, and extra microphones can usually be added.
Allowed frequency bands differ by country, so confirm the exact band of the microphone against the regulations of your target market before ordering.
Lithium is lighter and charges faster but needs battery transport documents. Lead-acid is cheaper but heavier, which adds freight cost.
Our karaoke lines start from 200 pcs per model, and mixed models in one container are welcome.
