Right, but as mentioned in the article, if your phone has no power, it doesn’t matter what you have loaded on it.

PowerCore Solar 20000 - Anker US

Compatible with iPhone 12 series, iPad mini 5, Android smartphones and tablets (including the Nexus 7), and other USB devices. I bought it at a 35% off discount when on sale, so hopefully not as bad of a purchase decision as the Robin, and as I mentioned, I like its other characteristics including ruggedness and water resistance. Given the increasing frequency of wildfires and earthquakes here in California, I feel like this would be a good addition to an emergency kit kept around the house or in a car. The following graphs show the differences between the manufacturer’s specified energy density (Wh), energy consumed during recharging, and energy delivered by the USB-C port for the Anker PowerCore Solar 20000 and Nitecore NB20000. One Backpacking Light community member found that a larger solar panel attached to a smaller PBC worked well.The battery technology utilized in this power bank is Lithium Polymer (LiPo), which ensures long-lasting power and reliable performance.

On the NB20000 I tested, the USB-C input-only port was dead, which didn’t seem to affect any test results. Even under optimal summer conditions, it would take more than a week for an empty Anker PowerCore Solar 20000 to recharge fully. Tables from the BatteryBench test results can be found scattered throughout the rest of the article in the relevant sections. 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. Still, it only needs 90 minutes to be recharged, which you can track using the Intelligence IPS Screen.The ports on the top edge consist of two USB-A ports for output and one micro USB port for charging the battery itself. On the other hand, using PBC low power mode overnight wasted barely any energy: Chart comparing energy wasted by overnight recharging of earbuds using low power mode. I almost always use low power mode with the Nitecore because my iPhone gets quite hot with the “normal” power mode.

Anker, Apple, and more compared The best power banks of 2023: Anker, Apple, and more compared

Based on what I’ve been reading about solar panels peak output is somewhere around 14W/square foot, and this being about a tenth of a square foot, you can probably expect a 1. However, to ensure compatibility and best performance, we strongly recommend using your device’s original cable, a third-party certified cable (such as MFI) or the included cable. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. Featuring fast charging capabilities, the Anker PowerCore 20000 allows for quick replenishment of battery life.Conversely, if you want as much power as possible, check out the iMuto Portable Charger X6 Pro, which also has a USB-C port and supports pass-through charging, making it our Editors' Choice for larger batteries. My advice is to use the built-in at high altitude where the UV is stronger and the temperatures lower, or to not use the solar panel at all and keep the Powercore in shade so it lasts the longest time, to not use solar at all and carry more Powercore, or invest in a larger panel (21W is a good product) and keep Powercore in cooler shade. Previously, Ryan Jordan published empirical guidance in this article’s “Charging Batteries” section if you don’t want to dive into PBC testing. In testing, it added 28 hours, 5 minutes to an iPad streaming full-screen video over Wi-Fi at maximum screen brightness. Ajay reviews phones, tablets, accessories, and just about any other gadget that can be carried around with you.

Anker Power Bank, USB-C Portable Charger 20000mAh with 20W

After examining these four portable battery chargers with a comprehensive suite of tests, I know I could get enough data needed to make a good decision based on a limited BatteryBench protocol. It lacks USB-C for charging MacBooks and other devices like Anker's PowerCore+, but it's also smaller, lighter, and less expensive. Additionally, a quick installation guide is included to assist users in utilizing the power bank efficiently. The better your problem and question is described, the easier it is for other Anker owners to provide you with a good answer.The non-minimalist one you’d potentially keep in the car for when you flee in a more controlled way, not running out a building, there you’d have lot, and of course the car, so more water, more clothing. Due to recharging inefficiencies, all the PBCs consumed more energy than the manufacturer specified.
