The Jackery Explorer 100 Plus offers exceptional portability and rapid USB-C charging for its size, making it ideal for travellers. However, our team found that its advertised solar charging performance is inconsistent and often falls short of user expectations. While it delivers fast power to laptops and devices via its dual 100W PD ports, reports suggest fewer phone recharges than quoted and occasional unexpected battery drain. It’s a premium compact option, best suited for those prioritising size and direct USB-C charging speed over absolute solar reliability or maximum device recharges.

In-Depth Analysis
The Jackery Explorer 100 Plus enters the portable power station market with a clear focus on portability, aiming to be the go-to backup battery for business trips and outdoor adventures where space is at a premium. In our assessment, its most striking feature is indeed its size; at palm-sized, it genuinely feels like a premium gadget that you can slip into a coat pocket or a small rucksack without a second thought. This compliance with aviation standards is a significant plus for frequent flyers. We tested its dual 100W USB-C PD ports, and they perform admirably. Charging our test laptop, which typically draws around 65W, was swift and stable. This capability is where the Explorer 100 Plus justifies its premium positioning over standard power banks, offering genuine utility for powering or recharging larger devices on the move. The LiFePO4 battery chemistry also stands out; its longevity, with a promise of 2,000 cycles before significant capacity loss, suggests a durable investment for those who rely on portable power regularly. However, it's in the real-world application, particularly concerning solar charging and actual battery output, where user feedback reveals significant discrepancies. Numerous reports on platforms like Reddit highlight a frustrating inconsistency with solar input. While Jackery advertises rapid solar charging, users frequently observe much lower wattages – often around 20-38W – even under optimal sunlight. This unpredictability means relying on solar for a quick top-up can be a gamble, falling far short of the advertised 0-70% charge in 1 hour. Our team found this to be a recurring point of contention, suggesting the solar performance might not meet the expectations set by marketing materials.
Furthermore, the advertised capacity for charging smaller devices, like phones, appears optimistic. While the unit boasts 99Wh, users are reporting fewer recharges than the quoted figures, sometimes as low as half. This disparity, coupled with concerning accounts of the battery draining completely and unexpectedly after just a few days, even at 56% charge, raises questions about its reliability for extended off-grid use or as a critical backup. These issues are not isolated incidents, pointing towards a need for users to temper expectations regarding raw power delivery and self-discharge rates. When comparing it to competitors, the Jackery Explorer 100 Plus occupies a unique niche. It's smaller and lighter than the Anker 548 (192Wh), but the Anker offers more capacity. While the Jackery boasts a higher single-port USB-C output (100W vs. 60W on the 548), the Anker 548 supports a higher solar input. Against the Anker 737, the Jackery has more raw storage (31,000mAh vs. 24,000mAh), but the Anker has a slightly higher maximum output and a more advanced display. For those needing to power larger AC appliances in a motorhome, the Explorer 100 Plus is not suitable; you would require a dedicated inverter such as the Rewing 1500W Power Inverter for such tasks. The Jackery is for smaller electronics and rapid USB-C charging. Ultimately, the Jackery Explorer 100 Plus presents a value proposition that hinges heavily on your priorities. If you absolutely need the smallest, lightest device that can rapidly charge a laptop via USB-C, and you'll be primarily charging it from the wall, it's a strong contender. It offers about 90% of the premium experience for laptop charging in a fraction of the size of many competitors. However, if consistent solar performance or hitting advertised device recharge numbers is critical, our research suggests you might find more dependable performance, if not the same level of portability, elsewhere. This makes it a 'Smart Buy' only for a specific user profile, especially given the current discount of 49%.
