Abstract: An electronic device includes a connector for connecting to a second electronic device, a battery and an amplifier. The battery is configured for charging a battery of the connected second electronic device, and the amplifier is configured to amplify one or more communication signals. The one or more communication signals are received by and/or transmitted from the connected second electronic device.

Abstract: An electronic device includes a housing, a removable connector comprising a base portion and an upper portion on the base portion, and a recess in the housing accommodating at least part of a removable connector, wherein at least part of the base portion is positioned in the recess. The upper portion of the removable connector comprises a male connecting element for connecting to a second electronic device. The electronic device further includes a battery configured for charging a battery of the second electronic device via the removable connector when at least the part of the base portion is positioned in the recess, and the male connecting element is coupled to the second electronic device.
