Out of the four mid-range panels we tested, the RAVPower 16W was on the lower end of the scale concerning overall performance. This model was relatively slow to charge our battery packs and iPhones during testing and struggled to charge two devices at once due to the loss of efficiency with the small size of the panel. It is lightweight and easy to use, making it a good option for those who don't want to invest too much into their solar charger purchase. This product's strength is its consistency, which places it between the Sookoo 22W and the PowerGreen 21 in terms of overall performance.

|Pros||Lightweight, durable, reasonably priced||Inexpensive, efficient, user-friendly, excels in partly cloudy conditions||Relatively lightweight for panel type, inexpensive, charges devices efficiently||Powerful, works well in partial sun, cheaper than other laptop compatible options||Efficient for its size, durable, rigid design makes it easy to prop up, designed and built in the US|
|Cons||Failed to charge multiple devices at once, lacks efficiency||Bulky, heaviest weight||Ineffective if relying only on solar for power, less durable than other battery packs||Bulky, heavy, hard to set up, complicated adapters for laptop charge||Expensive, large, hard to transport, lacks storage pocket|
|Bottom Line||This panel received average scores in almost all metrics; it's relatively efficient and comes at a reasonable price.||We were impressed by the BigBlue's ability to charge our gadgets quickly and reliably; its reasonable price is the cherry on top.||An efficient, compact battery pack with a 2W solar charger on it; out of the panels of this style, the Renogy is a top performer.||The X-Dragon 40W is the largest panel we tested and works relatively well for charging a laptop, though it is cumbersome and heavy.||For a rigid, efficient panel that is well-made and reliable, look no further than the 14W from Suntactics.|

Our Analysis and Test Results
The RAVPower received average scores overall in our performance comparisons. There were no categories where the panel truly failed, yet none where the model visibly excelled. This lands the RAVPower right in the middle of the road concerning performance and efficiency.
Charge Interruption Recovery
The 16W from RAVPower struggled to provide a steady charge to our battery packs after multiple interruptions. Unlike the Anker PowerPort Lite 15, the Anker PowerPort 20, and the Instapark Mercury 10W, the RavPower 16W did not perform well in cloudy conditions and continued to disconnect when shaded. With an iPhone 6, the panel would disconnect and then have trouble reconnecting to the phone when interrupted. We found we had to manually reconnect the phone to the panel, which is an issue.
To test charging speed side by side, we plugged in dead batteries to the panels and charged them to full while timing the process. The RAVPower performed moderately well in this metric, charging our battery pack from 0% to 38% in three hours. This is less impressive than the Anker PowerPort 15W, which charged a full 10% more in the same time. Additionally, the Instapark Mercury 10W charged our battery to 50% during the same amount of time. Though the Mercury is also has a three-panel design, it is much more efficient than the RAVPower, even though it technically has a lower wattage overall.
Multiple Device Charging Speed
In the category of mid-range panels, the RAVPower performed similarly to the Instapark Mercury 10W as it attempted to charge multiple devices at once. Since so much power is lost due to inefficiencies in the panels, the amount of wattage that makes it to each USB port is relatively minimal, reducing the charging speed significantly. The RAVPower struggled to sustain a charge to two of our batteries at once. For a product that performs better in this metric, check out a more powerful panel, such as the BigBlue 28W.
The RAVPower 16W got a bit of a lower score regarding durability since the solar cells themselves seem a bit less durable than the majority of other panels of similar design. Though we did not see any damage during our testing period, the cells were not well-integrated into the panel, like the Instapark Mercury 10 or the iClever BoostCel 12W. This is a small detail, and overall the design is quite similar to all the other fold-out panels in this review. The eyelets are reinforced, making the panel easy to hang up to gain full solar rays or to suspend from a pack when hiking. This feature is nice, as some panels, like the iClever 12W doesn't have this capability and relies only on Velcro to make the panel stand up on its own.
Weight & Portability
Weighing only 15 ounces, the RAVPower 16W is very lightweight for having a three-panel design. It weighs less than both the Instapark Mercury 10W and the iClever BoostCel. There is a wide range of weights and sizes among these panels, and it's up to you to figure out which design best suits your needs.
This panel is a good option for someone looking for a lightweight, moderately efficient panel that is inexpensive. The RAVPower costs less than our Best Buy Winner but honestly doesn't work as well. For a decent panel, that is inexpensive, for someone who probably won't be relying entirely on solar for power, the RAVPower is a good option.
As mentioned above, the RAVPower is a reasonably priced panel. Sold online for $66, it is half the price of most of the 20W panels. That said, our Editor's Choice award winner, the BigBlue 28W delivers double the power for $6 less. The BigBlue is effective, powerful, and less expensive than the majority of the panels in this review.
In general, the RAVPower is a decent panel for the price. But, it failed to perform at the level of our top-ranking panels in our performance comparisons. For an inexpensive, fairly reliable panel, this one does the job.
