It packs plenty of capacity and features two USB-C ports and one USB-A port, making it perfect for charging multiple devices at once. The promotion is available on Woot and knocks 67% off the usual retail price. You don't want to miss out because once it's gone, it's gone. This one is an easy one to pick up We always recommend grabbing a power bank with at least a 20,000mAh capacity. A 20,000mAh power bank has just enough power to charge smaller devices like phones multiple times, making it a valuable accessory to have with you. Plus, a 20,000mAh power bank can go with you anywhere, even on planes, which is great if you're planning to travel. The charging capacity will also let it charge larger devices like tablets. However, it will take longer and will likely use most of the power bank's charge capacity. The good news is that it can handle a variety of products with just one device. For charging power, you're looking at 20W max when using a single USB-C port. If you're trying to use all the ports at once, Amazon says this model can output 15W max. It's not the best output we've seen on a power bank, but it's also not bad when this power bank costs just $13. This model also comes with a USB-C to USB-C cable. In addition to all of the above, Woot also provides a 90-day warranty for the product that will cover any defects. If you want something cheap and useful, the Amazon power bank is going to be a good choice. Again, it's not going to be the most powerful model out there, but it's an easy one to recommend if you're trying to stick to a budget.
