Anker PowerCore Solar 20000, 18W USB-C Power Bank 20,000 mAh with Dual Ports, Flashlight, IP65 Splash Proof and Dustproof for Outdoor Activities, Compatible with Smartphones and Other Devices

Product Information

On the NB20000 I tested, the USB-C input-only port was dead, which didn’t seem to affect any test results. It’s hard to say if Nitecore has consistent quality problems based on a sample size of only two units. Selection advice

Maybe you don’t want to become a watt-hour weenie. To help choose the perfect portable battery charger, I could create complex formulas based on test results, hard-to-find specifications, and lots of assumptions. When this article was written, the Nitecore NB10000 and NB20000 portable battery chargers seemed to be the highest-performing models available, though they have had some issues. Testing isn’t that hard if you are determined to find the best PBC that meets your needs. The Anker PowerCore 20000 is a power bank capable of simultaneously connecting a maximum of 2 devices. It features a sturdy housing made of polycarbonate (PC) material, which provides durability and protection against potential damage. This power bank is compatible with various chargers, making it a universal choice for users. With LED indicators, it offers convenient and clear visual cues for battery status. Recharge PowerCore using either the micro USB or USB-C ports. Micro USB cable included. USB-C cable not included. The USB-C port is input-only and cannot charge other devices.Simultaneous Charging: Twin USB ports allow you to charge two devices at the same time. The USB-C port cannot charge other devices. These combined are typically losing about half the energy, means you’re likely going to see half the effect of what you’d calculate just by the size of the panel. The Anker PowerCore Solar 20000 includes a built-in flashlight: The Anker PowerCore Solar 20000 showing three white LEDs at one end. No matter what you’re using, Anker’s built-in PowerIQ technology tanks up your devices at speeds of up to 18W. Just plug in your USB-C cable around the campfire, and watch your battery % shoot right up.

Anker PowerCore Solar 20000 review Anker PowerCore Solar 20000 review

Due to recharging inefficiencies, all the PBCs consumed more energy than the manufacturer specified. They also delivered less than specified energy due to power conversion losses.

Physical Assessment: PBC weight and dimensions, evaluations of button and light usability, case design, and USB port quality. The USB port cover on the Anker PowerCore Solar 20000 is hard to insert and remove. However, it helps provide IP 65 “water-resistant” protection: The Anker PowerCore Solar 20000 with three out of four indicator LEDs glowing and the port cover under a USB cable. It seems like a bad idea to risk damage to smartphones, satellite communicators, and other expensive devices by using PBCs from little-known brands.

Because Lithium dislikes heat less when empty, solar would be better at turning it from 0% to 20% so you’d get more success when it is empty. If not empty, if you used it each night and then left in sun, then you’d fair less well with the chemistry. Here are the PBCs that have been tested with BatteryBench and show the highest numbers that are here today – but might be gone tomorrow. Highest delivered energy density You need experience with your gear on your trips to judge how much PBC capacity you require. Previously, Ryan Jordan published empirical guidance in this article’s “Charging Batteries” section if you don’t want to dive into PBC testing.PBCs in the 20,000 mAh class also had an 8% difference between the highest and lowest specified internal battery capacity: Specified Watt-hours for each 20,000 mAh class PBC. Longer is better. Superior Safety: Anker’s comprehensive MultiProtect safety system includes overcharge protection, short circuit protection, temperature control, and more. Solar charging is subject to sunlight intensity and panel conversion rate, so it may take several days to recharge PowerCore. We recommend recharging PowerCore to 100% before traveling.

PowerCore Solar20000 can charge devices while solar recharging simultaneously. Pass-through charging is not supported while PowerCore recharges via the USB-C port. Nitecore PBCs are lighter than Anker PBCs due primarily to the materials used (carbon fiber frame and panels on the Nitecore vs. plastic on the Anker): Chart comparing PBC weight in grams. Lower numbers are better.
