I've bought too the Anker's SoundCore Pro speakers and some of their great cables trough AliExpress (order no: 88282799611432), which arrived in perfect condition here in Romania (~6 weeks).
After I got home from Postal Office where I had to pay for customs clearance (VAT: $ 15), I've put them to work: a brilliant and rich sound, incredible for its size. I was really stunned, an unforgettable 2 hours experience (I have to admit that I'm not an audiophile though and never had such small speakers -- my intention was to use them mainly at night in a quiet environment i.e.: audio-books).
I've put the speakers to charge as I had to leave home after those 2 hours for a meeting.
The joy ended when I've got home after 4 hours: the speakers would not turn on anymore, there was a smell of burned plastic in the whole room (which still persists in a smaller amount even today!) and a trace of smoke was behind the speakers. I felt sorry for them... they were just gorgeous moments ago and then...
Since then I had opened a dispute on AliExpress and I hope for refund.
Such a pity, I own some Anker products (PowerPort+, PowerCore+, cables), but newer had have any problem. I even gave gifts to friends consisting in Anker products -- non speakers!
Here in Romania, we have some retailers which sell most of Anker products -- but not their speakers -- strange! (i.e.: https://www.easycharge.ro/anker
And again, a shame as what seems to have burned after opening gently the unit with some phone opening tools (I'm an IT engineer and did not resist to find out what seems to start a FIRE
on our house) was some power circuit, and not the DSP/audio one (see the melted rubber in the video, near the power button! Underneath it, all the PCB with some circuits were really FRIED).
And here are more evidences, including a video:https://1drv.ms/f/s!AuVSiLdo71R6gR-xOLBDl7JwC3WV
I did not lost trust in Anker products and their quality & good products, but such exceptions should be avoidable in the future. There IS A MAJOR DESIGN FLAW in SC Pro though, as I've seen that I'm not the only one complaining.
Now, there are two proposals made by Anker on AliExpress:
1. Refund for a returned product -- I can assemble it again and send it, but given the shipment and customs costs I rather not accept this option.
2. "Hi friend, can you try to charge with another cable or wall charger to test?
Also please provide a video, we will check for it, thanks!" -- well, QED; what's to test now?
A good day and hope Anker's warranty is on par with my expectations!
