Best Portable Chargers And Power Banks 2021
The Zendure SuperMini 20W is the complete package when it comes to recharging a smartphone or other small electronic devices on the go. It’s compact and light, about the size of a deck of cards and as heavy as the iPhone 13, yet its power rating is higher than any we’ve tested. If you’re looking for a power bank that you can easily slip into your pocket or purse on the way out the door but still packs enough juice to charge multiple smartphones up to three times, this is the one for you.
The Zendure has one port on each side: a USB-C PD port on the other side that works for input and output (meaning that’s how the power bank charges), and USB-A port status only for output from one. In our tests, we measured a maximum of 18.6 watts and a maximum of 19.3 watts from the USB-C port and a maximum of 16.6 watts from the USB-A port. While these figures are slightly lower than its rated output of 20W, the SuperMini is still powerful enough to charge multiple devices at full speed from two ports, or to charge two devices simultaneously. one at a slightly lower speed. With a whopping 10,000mAh capacity, you can fully charge your phone three times (or make friends instantly by charging strangers’ phones, the “cigarette bomb” of the digital age .

The exterior of the Zendure is a hard, glossy, nearly scratch-resistant plastic shell. It comes in different colors (red, green, black, silver, blue and pink) and, measuring just 3.1 x 2.2 x 1 inches, it fits in the palm of your hand. Weighing in at 6.4 ounces, about the size of a hockey puck, it’s lighter than any other 10,000mAh power bank we’ve tested.

The SuperMini drive is backed by Zendure’s two-year warranty, the longest of any brand we’ve tested, which should give you plenty of time to test it and make sure you don’t have any problems. . We’ve also had great experiences with Zendure’s customer support in the more than five years we’ve reviewed its products.
Another major problem with the SuperMini is the lack of built-in cables. We’d rather have built-in cables to charge our devices than give and take our own – they take up more space, get messy, and get lost easily. And unlike our other options, which can be charged with cables or built-in plugs, the SuperMini requires a separate cable (one included in the box) to recharge. But we think the fact that it packs a lot of power into a small package outweighs the small burden of packing a separate charging cable or two. It also means that the SuperMini can charge a variety of different devices, especially older ones that don’t use the new connectors.
We don’t like the raised panels on the SuperMini’s main surfaces, which make it look like a small hard suitcase, but it’s a good quibble. In addition, these charges make the power bank easy to identify by touch among others in a wallet or bag. They also add more grip compared to other models we’ve tested that have a completely smooth surface.
If the Zendure SuperMini 20W is not available and you want the next best thing in terms of capacity and portability: get the Anker PowerCore 10000 PD Redux or the Anker PowerCore Slim 10000 PD (depending on the price and the shape and color you choose love). Both models have the same capacity as the SuperMini (10,000mAh) and are almost pocket-sized, although slightly larger. The SuperMini weighs 6.4 ounces, the Redux weighs 6.8 ounces and the Slim weighs 7.4 ounces. Like the SuperMini, both models have a USB-C PD port capable of charging a smartphone or other portable device (and charging) at full speed, as well as a USB-A port .
