Our take on the Cillso Portable Bluetooth Speaker, Bluetooth 5.4, 20W HD Stereo Sound, 20H Playtime, RGB LED Lights, Ipx7 Waterproof, TWS Pairing, Wireless

The Cillso Portable Bluetooth Speaker is a 1.22 lb cylindrical battery speaker rated at 20W RMS, with Bluetooth 5.4, IPX7 waterproofing, a claimed 20-hour playtime, RGB lighting and TWS pairing for linking two units. It also plays from TF card, AUX and USB, and adds a 3-band EQ plus eight light modes. Its only recorded daily price is $26.99, so there is no lower or higher point in its history to compare against yet. At that price it sits at the budget end of 20W waterproof speakers.

Best forBuyers who want a cheap waterproof speaker for showers, pools and patiosPeople who like music-synced RGB lightingAnyone wanting a second unit later for TWS stereo pairingListeners who still use TF cards or AUX cables
Pros
  • IPX7 rating means it can survive being dunked, not just splashed
  • Bluetooth 5.4 for stable pairing with phones and laptops
  • 20W RMS from dual 52mm drivers is solid output for the size
  • Multiple inputs: TF card, AUX and USB alongside Bluetooth
  • 3-band EQ lets you cut boomy bass or lift treble
  • TWS pairing doubles volume or splits into stereo with a second unit
Cons
  • One speaker unit, so stereo separation is limited without a second Cillso
  • 20-hour playtime is a manufacturer claim and likely drops at high volume with lights on
  • RGB lighting drains battery and is not to everyone's taste
  • No app, no smart features, no voice assistant support
  • Brand is little known, so long-term durability and support are unproven

Questions and answers

Is the Cillso speaker worth $26.99?
At $26.99 it is cheap for a 20W IPX7 speaker with Bluetooth 5.4 and TWS. If you want a rugged, loud speaker for outdoor use and do not need premium sound, it is reasonable value.
How does it compare with a JBL or Anker speaker?
It undercuts major brands on price and matches them on paper with IPX7 and 20W. Expect less refined tuning, weaker bass and less proven long-term reliability than a Flip or Soundcore model.
Does it really last 20 hours?
The 20-hour figure is a manufacturer claim, likely measured at moderate volume with lights off. With RGB on and volume high, expect noticeably less.
Can I pair two of them together?
Yes. TWS pairing links two Cillso units for double volume or stereo sound. Both speakers must be the same model.
What comes in the box?
The retail set includes the speaker, a charging cable and a user manual. Check the listing for whether an AUX cable is included.
When is it cheapest?
The only recorded daily price is $26.99, on October 29, 2026. There is no lower price in its history yet, so watch for holiday sales.
