Solar Power Banks Shine As Summer Travel Heats Up
High-capacity power banks have been promo staples for years, but 2025’s breakthrough is the adoption of monocrystalline solar panels that charge devices—and themselves—faster than ever. Unveiled on the PPAI Expo floor, the latest 10,000 mAh models harness daylight to top up an iPhone in just over 30 minutes of sunlight, making them ideal giveaways for outdoor events, music festivals, and corporate wellness initiatives that encourage screen breaks outside.
The new housings feature a rugged rubber-over-mold, dual USB-C outputs, and an integrated LED floodlight—turning a branded charger into a campsite essential. Corporate buyers are bundling the units with adventure-themed merch kits or employee safety packs for field crews who can’t always reach an outlet.
4Merch offers logo laser-engraving or full-color UV decoration, plus optional variable-data serialization so IT teams can track assets. Standard production with solar cells is only less than two weeks, so brands can still catch the early-summer travel window.
