I have purchased dozens of Anker products, from chargers to batteries to the charging plugs. I even bought a few Bluetooth speakers over the years. When I purchased this one, it was to replace its older model, which I had for about 5 years. Worked great, but the battery was finally wearing out. The natural expectation was to purchase the newer model because it had a new, fresh, long-lasting battery. I WAS WRONG!This is the first blemish on Anker’s record in my relationship with the company, but I’m deeply disappointed. This speaker is meant for the shower. Low usage over short duration, but when I go to turn it on it’s already spent. How? I didn’t even use it but once since I charged it two days before. I’ve missed my window to return it, but BUYER BEWARE!

I received this speaker 5 months ago at the beginning it was ok, not lasting the 8 hours advertised, i didnt used this everyday, like 2~3 times a week but last week i noticed that battery was dying way faster like 3 hours of usage, and time decreasing with every use, now it wont even last 2 hours, what a piece of junk, not buying anymore from anker, i cant even ask for a replacement because i live outside us and they ask to send the broken item and form where i lived doing that, the shipping will cost me like $90 so NOPE.
