Charging your item with Reiki
Reiki is a universal energy that balances and empowers. As a reiki master, I will purify and charge one personal item of your choice: your favorite crystal or power stone, jewelry, favorite pen for writing, craftsman tools, protective equipment, clothing, container for something important, a vehicle, and yes even electronic devices...
Reiki energy works from a distance, so simply describe the item to me and I will charge it up from here in the mountains of Japan within a day (our timezones are probably quite different!).
The charged item will be infused with a well-balanced energy and empowered to its purpose. The charge lasts until other energies in the environment or misuse gradually deplete it. Through care, you can maintain it yourself for quite some time, and it is possible to do a recharge.
(Please note that broken items will not be physically repaired, and while reiki can sometimes soothe a glitchy device, it can't recover from malware or bad software updates...)
If you play D&D, this is basically like creating a +1 magic item that lasts until it is damaged or drained by continued contact with a malevolent influence within a 30' radius...
