The present invention includes a portable power supply having a housing that encloses a battery. Booster cables protrude from the housing and are electrically connected to the battery. Electrical clamps are attached to the booster cables and may connect to electrical terminals. The housing may include a clamp anchor integral thereto. The clamp anchor may include an anchor base and an anchor finger, wherein the anchor finger is generally perpendicular to the anchor base. The electrical clamp may be secured on the clamp anchor. The present invention further includes a booster cable with an electrical clamp that has a clamp cover rotatably mounted on the electrical clamp. The clamp cover may cover some of the electrically conductive portions of the electrical clamp and/or provide additional positioning of the electrical clamp on the clamp anchor.
