Everybody on our gift list who got a new iPhone is going to get an Anker Nano Power Bank (22.5W) this year. This cute little charger is perfectly sized to sit beneath your favorite smartphone, plugged into the USB-C port with a little plug that opens out or hides away for a sleek look. The “Fast Charge” moniker sets up high expectations. This power bank fully charged an iPhone 13 from dead to 100% in just over 90 minutes. While this stat is competitive for a small power bank, it’s about the same as several other top performers on this list. This Otterbox is a reasonably fast-charging product, but it’s on par with its peers on this list, not necessarily superior. Safely dispose of the defective device . If nothing else worked and the power bank is unsalvageable, the best thing to do is to safely dispose of it. The only secure way to do that is to take it to a designated collection point for small electronics and/or batteries. This way you can ensure the battery will get recycled and will not end up in a landfill where it would potentially release toxic substances or even start garbage fires. When you use a power bank, energy is expended in ways that don't charge your device. For example, when your power bank gets warm to the touch, this is internal resistance causing energy to dissipate from the power bank. These displays work similarly to an LCD screen but use LED technology to provide numerical or alphanumeric information about the charge level, usually in terms of a percentage.
Again, each power bank is different, so for the exact interpretation of a red LED blinking on your power bank, please consult the user manual. You can also get in touch with me via the comment section below and I’ll do my best to figure it out. LED Lights Blinking But the Power Bank Won’t Charge We like that this simple power bank is free of frivolous features. It serves its purpose perfectly and doesn’t pretend to be anything more than a reliable power bank. The easy-to-read LED display allowed us to keep accurate tabs on its battery life. Its rate of power delivery is right up there with the best banks on the market, but the bank itself is fairly low to charge.Four indicator lights convert battery levels — including one light that turns green when “fast mode” is engaged. Interestingly, this light turned green while charging an iPhone via the USB-C port, but not when charging earbuds via a USB-A port. It seems there is some kind of sensor in the OKZUthat engaged fast charging mode when the receiving device has a compatible battery. Neat. Compared to the first generation of the NB10000, the second generation offers increased USB-C output for faster charging. It also has a “low current mode,” which is useful for sensitive devices with small batteries such as smart watches and Bluetooth earbuds.
Compared to the more durable options we tested, the Fast Charge has an all-plastic casing that feels a bit delicate and cheap to the touch. It survived our drop test and continued to function, but it just doesn’t have the feel of excellent build quality. Still, it’s a perfectly usable power bank. The Anker Prime series of Power Banks, including the Anker Prime 27,650mAh Power Bank (250W) and the Anker Prime 20,000mAh Power Bank (200W), are for people who truly love to geek out on power banks. If you came looking for the absolute best power bank you can buy, this is the best we've tried. We reserved a dedicated section for a blinking red light because it’s a rather important one. Because there’s no universal power bank language, it can mean different things depending on each model. Here are the most common interpretations of the red light blinking on a portable charger:You need power for your phone: The 3,000mAh battery inside is plenty to keep your Apple Watch going, but that isn't enough power to get you even halfway charged on an iPhone 15, and even less on bigger phones.
The battery charge level of the power bank is just one function of the LED lights, albeit the most common one. But the LED lights can also communicate other things as well. Here’s a list of some of the most common issues that they might signal: There are also cool additional features to consider. Our favorite power bank has a built in charging plug so it can go right into a wall outlet. Some power banks have data about your charging devices. Some are just super small and cute. Which power bank is the best quality? That app is essential because there's a Find My feature built into the battery. It doesn't work like an AirTag over UWB, it's only Bluetooth, but it's useful if you misplace your battery in your office (or you have multiple batteries, like I do). To compile this list of the best power banks, we combed the market for the most popular, innovative, and well-regarded models — and then conducted extensive testing at home and in the field to determine the best model for every need and budget. We charged phones, cameras, laptops, and even other power banks. We dropped and lightly abused over a dozen models to determine durability and longevity. In the end, we were left with a clear understanding of which models are worth their weight and price tag. These are the best power banks on the market today.These days, many devices including phones, power banks, tablets, and cables claim to support “fast charging.” In reality, there is no universal standard for what “fast charging” really means. Each individual device has specifications that determine how much wattage delivery it can handle. Every element in the charging system — phone, power bank, and cable — plays a role in the rate of power delivery.
