The charger is made of quality material. I charged 2pcs Dolidada AAA 8800mAh 1.6V alkaline NiZn batteries (actually they have a capacity of about 1000mAh). After about an hour of charging they were hot, the voltage was 1.85V so I turned it off. Therefore 4 stars. I will also try to charge AA batteries and see how it will behave.
I didn't receive my package but the seller and Ali Express have refunded me back my money. excellent and thank you so much that's so nice of you.
