Charging only possible on computer?

Just bought the 1000x wireless headphones; if I understand the charging directions correctly, they can only be charged via computer?!! If so, I’m returning them because I don’t want to lug my laptop on vacation.

You can also use a network adapter of a Smartphone, for example, the Voltage in output is always 5 V, but use one with an Amperage not too high compared to that of a USB's PC (0.5A), you will load faster the headphones but risk damaging the battery.
