Our Analysis and Test Results
A compact battery pack with impressive charging speeds and a lightweight design.
Performance Comparison
Charge Interruption Recovery
With a 10,000mAh battery pack in a small package, this product recovers from interruption very well as long as the battery pack has a bit of juice in it. Much like other battery pack/solar combinations, this product works well when the battery is slightly charged. If you are relying only on solar, the small panel will have a hard time charging the 10,000mAh battery on its own. That said, even when the battery is close to empty, the BEARTWO held a steady charge to our small devices.
Charging Speed
Though it is the same capacity as many of the other small battery packs, the BEARTWO is an impressively fast-charging device. In fact, it charged our phone 28% over the course of our 30-minute test period. This is almost as much as its 42-watt competitor, which is astounding. For such a small battery, we were very impressed by its charging capabilities.
Multiple Device Charging Speed
The BEARTWO has two USB ports, earning it a commendable score in this metric.
Durability
In terms of durability, the BEARTWO showed no signs of wear and tear over the course of our test period. We carried this small battery in the bottom of our pack on day hikes and used it around town. It has a port cover for the USB ports and is weather-resistant, making it an overall very durable product. It continued to deliver solid charge over the course of our test period, showing that the battery is long-lasting.
Weight and Portability
This is one of the most portable products in this review. It is so small and light that we hardly noticed it when it was in the bottom of our backpack. Its compact size makes it easy to use and a no-brainer to bring on any excursion. Our measured weight for the BEARTWO battery pack/panel is 7.5 ounces, making it the lightest product in this review by a long shot. It seems like battery pack technology has significantly improved over the past few years since these small devices used to weigh as much or more as a fold-out panel. Nowadays, they are compact and significantly lighter, making them an ideal option for backcountry travel, where every ounce counts!
Value
The BEARTWO comes in at the same price as most of the other panels with this battery pack/panel design. This product is durable, compact, and charges devices quickly, making it well worth the initial investment. With such a reasonable price tag and solid scores across the board, this model boasts a great value.
Conclusion
This is a portable, lightweight product that delivers a fast charge to two devices at a time, via a USB cable. We applaud it for its simplicity and fast charging capabilities. That being said, we prefer using the BEARTWO as a battery pack, as opposed to a full-blown solar set-up, considering the size of the panel. It's a great backup for travel or overnight trips into the backcountry.
