Note for international users:

The charger that is included with your hoop is intended for use in the USA ONLY, or for places that have 110 - 120V current, NOT 220 - 240V. You will need a transformer to convert your local voltage down to 110-120V, otherwise if you try to charge your hoop you will fry the hoop and charger. You will of course also need a plug adaptor to change the American two pin plug into whatever kind of plug is used locally.

If you live in a country which has a different voltage from the USA or are going to be travelling and using your hoop in other countries, you may consider getting an international charger for an extra $20.

You CANNOT use one of the international chargers with a normal psihoop, and to change your existing psihoop to accept an international charger would cost $40 plus the charger.
