Good deal, just a shame it isn't waterproof.
Trying to remember the formulae from school...

I think that 5200mAh will be at 5V for usb...

So if it ran at 5A for an hour then that would be 25W for the hour...

So then that means it could deliver a steady 20W power for maybe an hour fifteen?

Or if it were running for 15 hours, then it works be averaging closer to 1W?

And all this assuming very good efficiency at converting stored electricity to sound...

Sorry - not picking on this speaker especially... Just playing with the numbers
wooo yet another speaker on sale! looks like a JBL Flip at 1/3 to 1/5 the price.. anyone compared the two?
oooh fake reviews alert. oh dear, watch out.

I have the Tronsmart Element T6 which is £36, but recently has been on a Lightning Deal ever so often which I got it on for £25 and honestly it's worth every penny! I would've definitely paid the £36!

EDIT: Just looked and it's on a Lightning Deal tomorrow at 5 : 35pm. It'll probably be the same price again, £25.

As far as i remember... watt in sound is not same as in electricity... you are playing ... but wrong game

Reading through some pages - eg Audio power ... It looks like Watts *are* SI Watts so they are the same across amplifiers, electricity and bicycles .. but it does seem that some audio system vendors like to measure their systems in terms of very brief peak power outputs that can be achieved, rather than what can be achieved continuously - eg there are pmpo (where the first p is peak) measurements Vs RMS (where the m is mean).

If the measurements across speakers/amps are vaguely consistent then I guess this is all ok... But reading a couple of forums, it seems like these power numbers need a little skepicism applied...

All good - thanks for letting me scratch a numbers itch

You are missing key numbers though and making some up. Firstly you are assuming that the speakers draw 5v volts and second you are treating them as if they drew a constant steady current like a light bulb. Worse still we don't what the impedance of the speakers are so have no way to confirm how much power is needed to drive them.

I can vouch for the T6 too, it's a really good speaker for the money.
How does this compare to the Anker Soundcore that was just on sale? Was going to get that before it expired

Not really guessing here.

I think I'm on solid ground using the fact that these batteries charge at 5V (this is usb spec - plus it's in the tao user manual, plus the amp/speaker can be run off a USB lead if the battery is flat) to then work this through to the deduction that their 5200mAh rating will be based on that same voltage.

Speaker impedance also feels irrelevant - no speaker is going to be able to output more audio energy than it consumes in electrical energy. I paid at least that much attention in school

Regardless I'm more than comfortable with my maths now. The 20W claim here is some kind of pmpo measurement. It's not a continuous 20W output for 15 hours - nowhere near. This isn't unique to this speaker - some variety of pmpo seems common in these descriptions.

Thanks for the questions - but I'm confident the numbers are ok.

Moving on
how to redeem th voucher as clicked "promotion available" then showing voucher collected then added to basket until last step for payment the price is still same.
any help please
thank you
Like most taotronics products I've looked at, fakespot thinks the reviews are mainly fake.

Thought it was an electric shaver till I read the title
Can't speak for this speaker but I've had a number of Taotronics speakers/headphones and all have been great.
Voted cold. Ive a few taotronics item, theyre all poor quality and just stopped working after a few months.

Got the Anker 20w wireless speaker(older one) for £32 recently and would recommend it. Plus it’s frequently on offer.

It takes input from the bluetooth, aux or microSD card.
