BigBlue 3 USB Ports 28W Solar Charger Review: Ideal for Camping?

Packing for a multi-day hike or heading out where outlets are scarce means portable charging solutions matter. After some hands-on field use, the BigBlue 28W solar charger proves to be a reliable backup when the sun is out, easily charging phones and small devices without any fuss, as long as it gets direct sunlight. Its lightweight, foldable design fits into a backpack without adding noticeable bulk, and setup is as simple as unfolding and plugging in.

Performance is heavily sunlight-dependent; on bright days, it can top off a smartphone in just a couple of hours, but slower charging in cloudy conditions is to be expected. While the three USB ports are useful, charging multiple devices at once can divide the total output, so larger gadgets may charge slowly or only if used alone. Some testers noted it still delivered useful power under partial shade, though not at full speed.

The build feels tough enough for repeated outdoor use, and the simple layout minimizes any setup confusion. One downside for some is that this charger doesn’t store power, so it only works when the sun is available—no extra battery included for after dark.

Overview of [Upgraded] BigBlue 3 USB Ports 28W Solar Charger

Setting up the BigBlue solar charger outside is simple—its foldable design and lightweight build make it easy to carry. When placed in strong sunlight, it reliably charged several small devices like smartphones and a power bank at the same time.

The three USB ports are convenient for multi-device charging, though sharing the power means charging slows down if all are in use. Direct sunlight is needed for the best results; shaded or cloudy conditions reduced performance noticeably.

Construction feels sturdy, and the panels seem tough enough for camping or hikes. However, it doesn’t store power for later use, and the lack of a lightning cable for Apple devices is a minor inconvenience. Still, for those spending time outdoors, it offers a practical charging solution if there’s plenty of sun.

Efficient Triple USB Charging

Charging three devices at once is practical when camping or traveling. During recent use, the BigBlue charger handled a phone, a power bank, and wireless earbuds simultaneously. All three drew power steadily under full sun.

Managing devices with different power needs can be tricky. He noticed when one device demanded extra current, the others charged slower, but everything eventually topped off. The system shuts off safely if conditions change, like shade or overheating.
