Our Verdict

The Qi 10,000mAh battery pack claims to charge devices wirelessly; we had trouble getting the wireless charge to work effectively and found the battery overall to be bulky and cumbersome. It was also the slowest of the three battery pack panels we tested, barely charging when left to trickle charge in the sun. With less-than-impressive charge times, we would not recommend the Qi. For a more capable battery pack/panel, check out the Renogy 15,000mAh, which is lighter and more effective than the Qi.

Pros Durable, useful flashlightInexpensive, efficient, user-friendly, excels in partly cloudy conditionsRelatively lightweight for panel type, inexpensive, charges devices efficientlyPowerful, works well in partial sun, cheaper than other laptop compatible optionsEfficient for its size, durable, rigid design makes it easy to prop up, designed and built in the US
Cons Bulky, slow to charge, only has one USB portBulky, heaviest weightIneffective if relying only on solar for power, less durable than other battery packsBulky, heavy, hard to set up, complicated adapters for laptop chargeExpensive, large, hard to transport, lacks storage pocket
Bottom Line The Qi is a durable but bulky battery pack that fell short in our charging speed metrics.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 Qi 10,000 is a battery pack that has one USB port, charges slowly in the sun, and has a clunky shape that deterred us from reaching for it frequently.

Charge Interruption Recovery


As was the case with the Renogy 15,000mAh and the RavPower 25,000, measuring the charge interruption recovery of the Qi was a challenge. This panel does not charge quickly in the sun, making small interruptions in solar delivery less of an issue. It's best to charge it up indoors, reserving the solar panels for trickle charging purposes if you have time to leave the panel out in the sun for hours. If a device is left plugged into the battery, small interruptions in solar power will not affect the overall charge rate of the device.

The Qi is not the most efficient charger  nor does it utilize the sun very effectively.

Charging Speed


This battery pack was significantly slower to charge our phone than the Renogy. Over a half-hour period, the Qi charged our phone from 24% to 42% (18%). This charge time is significantly slower than the Renogy, which charged the same phone 23% in the same amount of time. We also ran into issues with the wireless charging system, which was not intuitive to use. We were not able to get it to function with our test phones, though it appears that the manufacturer now lists tips on the Amazon listing.

The Qi was slower to charge our phone than the Renogy 15 000mAh  which makes sense since it is a smaller-capacity battery pack.

Multiple Device Charging Speed


The manufacturer claimed that the Qi has two charging ports; to be clear, the panel only has one. There is a USB-C port, but this is used only to charge the panel itself, not as an output port. This misinformation made us distrusting of the company, and product overall. It also means that the Qi earns a low score in this metric, as it is unable to charge multiple devices simultaneously. The Renogy 15,000 was our favorite battery pack for multiple device charging, as it is the most straightforward and most efficient of the three we tested.

Though the manufacturer claims the Qi can charge multiple devices at once  the battery is in fact only equipped with one USB port.

Durability


The dustproof, waterproof, and abrasion resistant silicone materials used in the construction of the Qi make it a very durable product. We had no issues with the performance of the panel over our three-month testing period; the battery still appeared brand new, even after a few months of use. The overall construction of this panel is of a slightly higher quality than the Renogy 15,000.

The Qi  shown on the right  is one of the bulkier of the three battery packs; it is durable but also heavy.

Weight and Portability


Slightly more substantial than the Renogy 15,000, but not nearly as bulky as the 19-ounce RavPower, the Qi lies in the middle of the three in terms of weight. This panel weighs 10.6 ounces, which is a little over an ounce more than the Renogy. All of these panels weigh more than most small-capacity units in this review because they have relatively large batteries included. The Renogy E.Flex 5W, for example, weighs just over six ounces; this model would be a much better option for backcountry use, considering its weight and ability to charge via solar.

Best Application


Much like the Renogy 15,000, the Qi is best used as a back-up battery pack when traveling or on weekend trips. The Qi is most effective when charged to full from a wall charger, rather than relying on solar to fill up its battery reserves. Slower to charge than the Renogy, the Qi is a less-ideal option for travel.

Value


With a list price of $30, the Qi comes at a decent price. However, due to its finicky wireless charging feature, single USB port, and mediocre performance overall, it isn't our first recommendation. The Renogy 15,000 functions better overall, making it an obvious choice over the Qi.

These hefty lights are fairly bright  though  which was a positive aspect of its overbuilt design.

Conclusion


The Qi power bank was not our favorite panel of this style. Its performance in our metric comparisons was lackluster, and the manufacturer's online claims make the panel seem more effective than it is. Overall, this panel is functional, but better models can be found in our fleet.
