not only is this the lowest price I have seen the X10 so far (as shown on 3xCamels), but you can apply an extra $28 off coupon at the moment as part of lightning deal.
this makes it a JBL Xtreme 3 size bluetooth speaker (cheapest on OzB shows $188 + delivery), for slightly under JBL Flip 6 deal price.
JBL Xtreme 3 is 29.8 x 13.6 x 13.4cm 1.97kg , W-King X10 is 31.52 x 13.49 x 13.97 cm; 3.37 Kilograms.
Xtreme 3 also has slightly smaller claimed speaker drivers with two 2.75 inch (70mm) drivers while X10 claims to use two 3.7 inch (93mm) Amazon US listing says 3.5 inch drivers, which is still much larger than JBL but looks like they are exaggerating driver spec for aussies.
Claimed amplification for Xtreme 3 is also 25w x2 (woofers) + 25w x2 (tweeters) while X10 claims 35w x2 + 10w x2.
Battery size for Xtreme 3 is 36.3Wh (equivalent to 7.26 V/5000 mAh), while X10 claims 56.1Wh (7.2V 7800mAh). Xtreme 3 claims 15 hours battery life (most likely at 50% volume), X10 claims 42 hours battery life (a bit optimistic IMO for 30% larger battery, I would guess this is only achieved at under 50% volume).
X10 has TF card slot and Aux in while Xtreme 3 does not have either.
one review claims their X10 refuses to hold charge, get's hot and is very slow to charge when plugged in. I don't know that user's specific situation, but all I can say is be smart about the battery.
W-King recommends 5v/2A input for charging, make sure you use a USB power adapter/charger with higher spec than 2A. I have another speaker (Xiaomi) which specifies 5V/3A input, and when I tried to charge it with a 1A and 2A charger, the speaker got hot just like the negative review mentions (I suspect it has something to do with the voltage boost converter for the 7.2v battery). luckily I noticed the heat quickly and didn't damage the speaker, but I always charge with 3A input now and it has been 2 years with no issues.
other than that all I can say is don't drain the speaker battery down to 0% every time you use it. keep it charged. it's even a good idea to charge it back up to full from 70% rather than not charging then use it for a long period or let the battery drain really low.
Thanks for the detailed specs in the post. Very helpful, especially for those unfamiliar with the brand.
Something about their brand name, WAN-King, makes me skeptical though…
