Dubbed “ The World’s Most Compact Solar Charger“, infinityPV’s HeLi-on portable battery features a retractable solar panel far superior to the chargers of yore. Weighing in at a tiny 103 grams, the HeLi-on packs quite the punch. Its 2600 mAh lithium-ion battery can be fully charged after only 2-3 hours of solar energy, containing the equivalent of 139% of the iPhone 6’s battery capacity. The solar panel can be pulled out or wound up back into the battery, adding to the convenience factor that already exists. If you are one of the many who finds yourself constantly at the mercy of a dies-too-soon battery, you’ll be pleasantly surprised about this bad boy can do. Head to Kickstarter to pledge for a July 2016 release.
