FAQ

For sure, but it might take a bit longer. Depending on the wattage, it can take up to 18 hours to fully charge The Battery. Ours only takes 2 hours.

Why doesn't The Battery come with a charger?
In short, this will help reduce electronic waste and encourage people to use their existing USB-C chargers. That's definitely a good thing, if you ask us.

How much of The Battery is used to fully charge a phone?
About 20% of its capacity.

How long does The Battery last?
This hasn't changed from previous designs. It'll last 40 hours at mid-volume with any Soundboks. When you turn up to 11, it gives you 6 hours for the Soundboks 4 and 8 hours for the Soundboks Mix.

Why doesn't my Soundboks come with a charger?
Due to the EU Radio Equipment Directive, our speakers no longer include a charger. This policy aims to reduce electronic waste by encouraging the use of existing USB-C chargers. If you need a charger, you can purchase The Charger separately.

Reviews

"The product is fine. But I tried to cancel this order less than five minutes after placing it because I found it $80 cheaper at another site. They did not cancel the order even though they had nearly a full work day to do so before it was processed by the shipping department on the east coast. It was shipped to my son out of state so returning it would be another hassle. The speakers themselves are amazing, but this transaction and their excuse was disappointing to say the least."

Soundboks Gen-4

"Purchased a Soundboks Gen-4 with a spare battery and charger a few weeks ago. Have been putting it through the test ever since in my new studio. As I have found with most new speaker systems, it did need a short period of break-in... After a few days of starting at lower levels and then cranking it up all the way I have found it is rock hard ready. It lives between 7-11. I can honestly state the sounds is excellent; loud and crystal clear. I'm in my mid 60s and have been rocking out for 55 years with many, many speaker and stereo systems. The sound from the Gen-4 is crystal clear, I can hear things in songs/tunes I've been listening to for many years that I never heard before, or even knew were in the tune... I plan to get another one and link them up in the near future. Rock-on! Gary"

Gut aber Kabel. . .

"Gute Performance und Ladezeit Wenn die Zyklen lange Zeit so bestehen bleiben bin ich sehr zufrieden. . . . Laden via USB C ist nice aber das Verbindungskabel zur SB nervt. . . ."

Super produkt! …aber der Versand… 🤦‍♂️

"Die box ist Sensationell super!!! Leider werden die Angegebenen Versandzeiten auf der Homepage und in der Auftragsbestätigung (diese sind unterschiedlich) bei weitem nicht eingehalten. Statt 2 bis 4 Werktage, dauerte der Versand 8 Werktage und daran war nicht DHL schuld."

— Matthias K. (2/5)

Top !!!

"Laut Hersteller sollen es 8-40 Stunden Betriebszeit sein. Ich habe die Box jetzt 1-2 Monate & Meiner persönlichen Erfahrung nach, auf voller Power reicht die Batterielaufzeit maximal 7 Stunden, was für mich kein Problem ist , da ich bei einem Angebot die zweite Batterie gratis dazu hatte. Bei niedriger bis mittlerer Lautstärke bin ich mit 40 Stunden locker über die Runden gekommen und ich muss sagen ich bin sehr beeindruckt von der Batterie und der Box !!! Danke dem SOUNDBOKS Team , beste Box und Batterie bis dato 2026"
