Our Analysis and Test Results
We were impressed by this panel, which came from a relatively unknown company. BigBlue has created an inexpensive, highly efficient product that charged our electronic devices with ease. Though it is a bit large and bulky, the extra size didn't matter because this panel got the job done.
For car camping or a backcountry basecamp where weight is not a huge concern, the 28W from BigBlue is an excellent choice. The positive features outweigh the negatives, as this panel will charge your devices quickly and effectively. It comes with a nifty auto-restart feature that comes in handy when the sun is intermittent, which occurred more often than we liked. During testing, we had multiple devices that required a charge; this panel acted as a basecamp charging station for our satellite phone, external battery, and two phones, keeping them charged for two weeks.
It performed consistently well in a range of conditions. Even if you are not a gadget-obsessed adventurer, this panel is an excellent option if you want a quick charge for a single device (and again, it's hard to beat the price).
Charge Interruption Recovery
One of the coolest features that our Editors' Choice has is the ability to recover from an interruption. Whether you are charging on a partly cloudy day, or the sun angle changes to cast a shadow over the panel while you are charging, the BigBlue has an auto-restart function that makes reconnecting to your device a smooth affair. Though the charge was slow with interruptions, this panel has less of a chance of not charging your device at all (after an interruption).
At 28 watts, the BigBlue now falls in the middle of the road in terms of wattage. We've started testing larger and larger panels over the years because the technology has improved such that companies can get powerful panels into smaller packages. This is just to say that the BigBlue did well, considering its size, in this metric.
It's right in the middle in terms of charging speed, with some larger capacity panels slightly surpassing it. In 30 minutes, the panel charged our Pixel 3 nine percent. This is impressive, though not the highest increase we saw from any panel. That said, its consistency across the board keeps it at the top of the list in our eyes.
Multiple Device Charging Speed
Though the BigBlue panel comes with two USB ports, we recommend only charging one device at a time, which will help achieve maximum efficiency. This multi-device function seems to be more of a marketing scheme than an effective way to charge electronics. That said, the BigBlue is the best-suited panel for this job because of its large capacity.
The BigBlue received high scores in our durability metric and is comparable to our other award-winning panels from previous test cycles. We had no issues with this panel performing in semi-wet conditions, and there were no signs of wear after a few months of use. Because it has a few more features than other panels (the ammeter and the auto-restart function), the BigBlue has a higher risk of breaking down in some fashion, though we had nothing but success when using this panel. The canvas material that covers the outside is durable and resistant to abrasions and wear, and the PET Polymer panels showed little sign of wear, even after months of exposure to the sun.
We liked that the updated panel has a zippered pocket with elastic straps inside to help you stay organized. The zipper also improves durability and protects your gadgets.
Weight and Portability
Efficiency and ease of use are a trade-off for portability and weight. The larger the panel, the faster it will charge your devices, and the more difficult it might be to fit into your backpack; the BigBlue is no exception. As our largest-capacity panel in this review, it should be no surprise that this product is also one of the bulkier options out there. If you're after a larger, heavier panel, it makes sense to go with the BigBlue since it will deliver the most charge to your devices in the least amount of time (and comes at an affordable price).
The other incredible aspect of this panel is the cost. The BigBlue is one of the least-expensive panels of its size. It delivers almost 30W of power and comes at an excellent price. Many panels we've reviewed are more expensive but also have a lower capacity; you do the math! This panel was one of our favorites because it humbly charged our gadgets quickly, with no extra frills or features. The simplicity makes it less expensive to produce, and in turn, keeps its price tag relatively low.
We absolutely love the BigBlue. It provides a consistent charge to our electronics in numerous situations, no matter if it's a partly cloudy day or there's a tree branch interrupting the continuous delivery of sunlight. Time and time again, it kept chugging along, charging our devices effectively. Though the panel has two USB ports, it performed at its best when a single port was in use. We decided to go all-in and give this panel our Editors' Choice Award, simply because it is the most efficient and fastest-charging panel in our fleet. Its incredible qualities trump weight and portability, as it is one of the larger panels we reviewed, and the price is just right.
