This compact model combines a traditional fold-out style panel with a battery pack; together, they make a neat little package that charges devices quickly and effectively. The Hiluckey Portable Power Bank contains a 25,000mAh battery pack and a 5W panel. Now, it takes a long time to get the fairly large capacity battery pack full using only solar power, but once it is full, it delivers a consistent charge to multiple devices at once. The only drawback to the panel is on the LED indicator lights; we noticed that three out of the five lights were very faint, making it hard to tell when the battery was full.

Our Analysis and Test Results
This panel performs well when the battery pack has some reserve battery in its power bank. It struggled a bit in terms of weight and durability.
Charge Interruption Recovery
Here we see again that panels with built-in battery packs tend to do better in this metric than those without. The Hiluckey is no exception, with its 25,000mAh battery back and small capacity panels. The battery pack/panel combination maintains a charge on cloudy days if the battery pack already has some juice in it; however, it takes a very long time to get the Hiluckey battery pack full using only solar power. If it has a little bit of charge, it can keep delivering power to another device through periods of intermittent shading.
Since the LED lights had a difficult time functioning, we couldn't tell how fast the integrated battery pack charged in full sun. We could, however, measure the speed that the battery charged our cell phone (Pixel 3). The phone was able to charge 26% over a half hour when plugged into the battery pack in full sun. With no sun, the battery pack charged our phone 4% over the course of thirty minutes. It greatly helps the efficiency of this panel to be in full sun.
Multiple Device Charging Speed
If the panel is placed in full sun, it does a pretty impressive job of charging multiple devices at once. When placed in full sun, this panel charged two battery packs 3% each over the course of 30 minutes. This is impressive when the size of the panel is taken into consideration. Most of its power comes from reserves in the power bank.
A leather case covers the fold-out panels, providing a significant amount of protection. The battery pack is a fairly substantial chunk of plastic that seems fairly durable from a construction standpoint. The downside to this panel was the fact that the LED indicator lights are hard to read. This is more of a design flaw than a durability issue, but regardless, made it hard to tell when the battery was full.
Weight and Portability
Here, the Hiluckey was a bit difficult to rate. On the one hand, it's small and compact, fitting easily into a daypack for hiking or traveling. On the other hand, its large battery pack weighs 18.7 ounces, which makes it difficult to carry on a long day out, as it adds significant weight to a backpacking kit.
The Hiluckey comes at a very reasonable price, especially when you consider that you are buying a fairly large capacity battery pack as well as a 5W solar panel. Other integrated panels cost more and work just as well as the Hiluckey, making it a product of fairly good value. The fact that the LED lights didn't work on our test model is a bit of a red flag in terms of the longevity of this product.
The Hiluckey excels in charging speed, charge interruption recovery, and multiple device charging speed. Its fairly high scores in these metrics though are very much a result of the battery pack being fully charged. Without reserve battery power in the pack, the panel would have scored much lower in all of these metric ratings and should be taken into consideration.
