There’s no rechargeable battery, but Kobo says the included AAA should last for months. The remote will only connect to Kobo devices that support Bluetooth for audiobooks, but the pairing process is as painless as connecting headphones. Once paired, the remote automatically reconnects when your Kobo wakes, requiring just a second or two before it’s ready to go. If you want to connect it to a different e-reader, a button on the front edge of the remote manually activates pairing mode.
In short, such fancy mechanisms may be beneficial in some cases, but they shouldn’t be a default choice.
