Can charge most smartphones two or three times (10,000 mAh). Nimble includes a 3.3-foot USB-C to USB-C cable in the box. This new version uses 90 percent recycled plastic (up 25 from the original) and comes in smaller plastic-free packaging. But Nimble's use of bioplastics and plastic-free minimal packaging at least reduces the environmental impact where it can be reduced. They use lithium, cobalt, and other rare metals whose supply chains are environmentally and socially questionable at best. Batteries are not environmentally benign.

The other reason we like Nimble best is because of its environmental efforts. There's also a smaller version with a 5,200-mAh capacity that tops out at 15 watts. The Pro version is bigger but doubles the capacity (to 20,000 mAh) and has a similar design with two USB-C ports that go up to 65 watts. It feels durable, comes in a snazzy new range of speckled color finishes, and has a bright lanyard loop that makes for easy carrying and helps you pick it out of your backpack. While Scott used the original for years, the new version has only just landed, but so far, so good. It's smaller than a deck of cards and can deliver 20 watts to charge two devices at once via a USB-C port on either end. At 6.2 ounces, it's one of the lightest on the market. The Nimble Champ topped this list for years, and now its successor is taking over by combining everything that made the original so good and bringing some welcome improvements.

Updated April 2024: We added power banks from Raycon, Sharge, and Fans Dreams, among others, removed several sold-out or discontinued chargers, and updated prices throughout. Be sure to check out our Best MagSafe Power Banks guide for Apple-specific portable chargers, and our Best Portable Power Stations guide if you need more power. But even if you're not living in an off-grid solar setup, good power banks will come in handy. This obsession started when Scott Gilbertson lived off-grid in a vintage RV, powered primarily by solar panels. To help, we've spent years working our way through all of them. There are hundreds of portable battery packs, and picking one can be confusing. But if you keep a battery-powered portable charger handy, all those situations are a thing of the past. Our memories on the boat are good ones including landing a few big fish and some long trips to Canada.Portable devices have a Murphy’s law–like ability to run out of power at the least convenient moment: as you step on the bus, right in the middle of an important meeting, or just as you get comfortable on the couch and press Play. My X21 takes all the worry out of boating and water conditions. Fishing for me is about making memories with my daughters and friends. I now have over 100 hours on the boat and look forward to hundreds more. I expect it to be as reliable as my previous Yamaha, which I ran for 19 years. My X21 is at least 1,400 pounds lighter than my last 21-foot fiberglass boat.

The lighter weight of my X21 makes towing a little easier on my truck and fuel budget. It’s easy to clean, looks great, and dries fast. The huge front deck and well-organized storage allow me to carry more than I need daily on the water. The best features of my X21 begin with fishability. Fishing with a guide who runs an Xpress, plus watching some of Bill Lowen’s videos convinced me that Xpress was the right decision, so I made the leap from fiberglass to aluminum in 2021. Functional, safe, and reliable without compromising performance. After 30 years and three bass boats, I decided I wanted a boat that fished any way I wanted and always brought me home. “I have enjoyed fishing and boating my whole life.
