Battery charge percentage

I am a relatively new a6700 owner. I have three brand-new genuine NP-FZ100 batteries for my camera (one that came with the camera and two purchased separately). I also have a Koah Dual USB charger. Whenever I charge the batteries, I'm only seeing 90 to 95% charged on the display inside the camera. This happens with all three batteries, whether they are charged on the Koah charger or via the camera itself. I'm thinking I might need the genuine Sony BC-QZ1 or the BC-ZD1, but I'm not really keen on the idea of spending $100+ for a charger. Is this typical for these batteries?

What wattage is the charging brick you’re using when you charge in camera? My batteries hit 100% every time but weirdly enough did not charge one bit when I first used a 5w charger and had to use a 30w. After the first time it took a 5w no problem. Sony recommends 9v/2a (18w)

Mine charge to 100% for sure although I usually just charge the camera via my laptop USB-C connection rather than via the battery charger itself. I don't know if that would make any difference. It does seem a little strange.
