Most modern chargers have a generous range of 100V - 250V. Your chargers will have the volts, amps and frequency (50-60hz) stamped on it in
tiny tiny writing.*
The biggest variation is the current output, with the crummiest giving 0.5A, and the best 3A or more. The crummy ones still work, but it takes ages to charge.
As a phone junkie, I use any branded USB charger and any cable, and have done for years. Today I'm using Sony, Nokia and LG chargers, and they're charging a One Plus, Huawei, Nokia Android, Google Pixel C, & some ancient LG Android. Cables are misc ones but from good sources (the nearest phone packaging/box).
It's pretty rare that a combination doesn't work. Maybe once every 2 years or so I hit a snag, and it's nearly always a faulty USB cable, not the charger itself.
I've had one cable that just didn't fit well - slightly worrying as I thought it might bust the phone. That one went in the bin.
Last thought: if you have a cover on the phone it's worth checking the cover isn't stopping the cable getting right into the phone's socket. That's just annoying, but in your case, unlikely.
*If you use unbranded chargers off eBay / local market stall, all bets are off. As is your house insurance.
