Powertraveller Falcon 21 Review

This solar panel has the one bright side of a 12-volt connection and a DC outlet. However, that didn't save the panel from its poor performance

Our Verdict

Along with lackluster performance, the Powertraveller Falcon 21 also has a substantial price tag for what it does. While it has a DC output and a 12-volt connection, the actual value of the panel is a bit off. Many less expensive options performed better.
12V Connection
Lots of different adapters for the DC outlet
Can't charge multiple devices

Our Analysis and Test Results

This solar panel performed poorly in terms of collecting sun directly or indirectly. It also lacks a second USB outlet, making up for that with a 12-volt connection and DC output. It's not particularly portable and it's a bit expensive. Overall this solar panel performed poorly in our review. It'd be best to check out other solar options.

Performance Comparison

Direct Solar Charging Speed

The Powertraveller Falcon 21 performed poorly compared to other models we tested. The three mono-crystalline panels received 810 mAh while in direct sunlight making Powertraveller Falcon 21, making this panel a poor choice for collecting sun.

Indirect Charging Speed

The Powertraveller Falcon 21 did poorly in this metric as well. In total coverage, it produced 13 mAh, which was one of the lowest outputs for any of the chargers. It essentially didn't charge. In partial coverage, it produced a mere 37 mAh. This barely makes a dent in terms of solar chargers. This panel needs some serious work if it should be considered a panel for an average user to buy.

Multiple Device Charging Speed

This device only has one USB port making it a grim choice for people looking to power up multiple devices. It does have a 12-volt connection as well as a DC output but those additional plugs weren't enough to sell this panel in terms of its ability to charge multiple devices. The inability to charge more than one device definitely turned down our ratings on this model.


The Powertraveller Falcon 21 is a midrange panel size in our review. It can handle some backcountry work. This panel weighs in at 18.4 oz. Folded this panel comes in at 11" x 6.2" x .4". Unfolded, it's 26" x 11" x .12". There are more portable models that provide more charge though.

Should You Buy The Powertraveller Falcon 2?

The Powertraveller Falcon 21 comes with a high price and less than ideal performance. The DC output and the 12-volt connection fail to justify the price for this panel. We would look to other models that have a better price-to-performance ration.

What Other Solar Chargers Should You Consider?

The Powertraveller Falcon 21 is an expensive solar charger that did poorly when it came to charging speed, portability, and multiple devices charging speed. This solar panel may be best suited for when you need a charger with a DC output or a 12-volt connection although there are better options for panels still.

If you're looking for a similar size charger check out the X-Dragon 20W SunPower which is significantly less expensive or try the Big Blue 28W which charges better, works better with multiple devices, and is less expensive.
