The RAVPower Super-C finished right at the back of the pack, earning one of the lowest scores we have seen so far. While it does have an impressive capacity and is compatible with the new power delivery USB charging standard, we overall weren't thrilled with its performance. It takes an incredibly long time to recharge and it is one of the larger batteries of the group, making it a pain to carry around in a coat or pant pocket. However, it is fairly convenient and can charge your devices a ton of time, but we would recommend other products over this one if you are looking for a charger specifically for larger, power-hungry devices.

Our Analysis and Test Results
This portable charger finished at the back of the group, just behind the Anker PowerCore+ 26800 PD. Both of these batteries are about the same in terms of portability and convenience, but the Anker fared a little better in our capacity tests. However, it was the Anker's dedicated wall adapter that gives it the edge, allowing you to recharge it in a fraction of the time that it takes to charge the RAVPower Super-C. However, the Anker does cost a bit more, but we would definitely recommend it over the RAVPower Super-C if you can afford it.
We started our quest to find the best USB portable charger of them all by comparing dozens and dozens of different batteries, then buying the most compelling models to test out head-to-head. We compared and evaluated the performance of each battery pack in a series of tests, grouped into four weighted metrics, with the Super-C's less than super results described below.
Responsible for the largest portion of the score for each product, our portability tests account for 40% of the overall score for each product. For this group of evaluations, we compared how easy it is to carry around each battery in a pocket, as well as its overall size and weight. As mentioned above, the Super-C is one of the largest batteries, earning it a 2 out of 10 in this metric.
This battery is definitely too large to be easily carried in the front or back pocket on most pairs of pants. It won't even fit in most pockets and it usually will stick out or be excessively cumbersome even if it does fit. However, you can fit in a few coat pockets, but you will definitely notice the bulk. It is also one of the heaviest batteries, weighing just over a pound!
The Super-C has a rectangular shape that measures just shy of 7" long and just over 3" wide and is 0.88" deep.
For our next group of assessments, we used a digital multimeter and resistive dummy load to measure the actual capacity of each battery with realistic discharge rates and looked at device-specific charging claims to determine the scores. The Super-C delivered an overall mediocre performance, earning it a 5 out of 10.
While this battery does have one of the largest stated capacities of the entire group, we were only able to pull about 57% of this out with our resistive load set to a 2.4 amp discharge rate. We repeated the test at a 1 amp rate and were able to get a small amount more out — around 60%.
However, the RAVPower Super-C did meet its manufacturer's claims regarding charging specific devices. RAVPower states that you can charge an iPhone 6S ten times, a Samsung S6 six times, or an iPad Air twice. Using those numbers, we calculated that it would be equivalent to charging a Samsung S8 5.1 times and found that the Super-C slightly exceeded this in our test, charging the phone 5.13 times before completely dying.
Next, we assessed and compared what additional features and functions each portable battery pack that make their overall use and operation that much more convenient. We specifically awarded points to batteries that had integrated device charging cables, built-in recharging methods, or included a flashlight, as well as the length of the warranty term and if you can charge multiple devices at the same time. The RAVPower Super-C did quite well, earning a 6 out of 10 in this metric, which is responsible for close to a third of its final score at 30%.
This portable charger can charge up to three devices simultaneously using its two USB-B and one USB-C output ports. It also has a decently long warranty period — 18 months if you don't register, 30 months if you do.
It also is compatible with the new Power Delivery standard, allowing you to charge certain devices much faster when using the USB-C port. However, it lacks any integrated cables or recharging methods and does not have a flashlight on it.
For our fourth and final metric, we timed and scored each power pack on how long it took to recharge. This accounts for the remaining tenth of the total score, with the RAVPower Super-C earning a 1 out of 10 for its exceptionally long recharge time.
This battery took almost 12 hours to recharge — much longer than any other battery we tested, even ones with the same stated capacity.
This battery is a bit too expensive to be a good value for most people, but it is one of the cheaper options that have the new Power Delivery capabilities, making it a decent value if you are looking for a portable way to recharge your Nintendo Switch or new MacBook on a budget.
Overall, the RAVPower Super-C 26800 is far from our favorite battery pack. It's big, bulky, and hard to carry and takes absolute eons to recharge. However, it does stand out by having Power Delivery capability, but this isn't enough to overcome its flaws for most people.
