A solar power conversion kit allows converting of a standard umbrella into a solar charging umbrella, which can then use solar power to charge electronic devices. The solar charging umbrella is self-sustained, capable of charging electronic devices in locations away from electrical outlets. The umbrella has a rechargeable battery that is recharged by sunlight. When charged, the umbrella's battery can charge devices when sunlight is not available. The umbrella supports simultaneous charging of higher power devices such as tablet computers.
