I’ve been using the ESR Power Bank for a few weeks now, and I even had the chance to test it at Glastonbury Festival. Considering my phone’s cable port is dead, having a portable wireless charger is fantastic. What I have to add, is that the ESR Power Bank is just great at everything it does as well, and it’s the envy of my friends any time I pull it out to show them. On top of consumer trading of excess energy, Power Ledger enables environmental commodities trading, making the exchange of commodities and renewables credits more transparent and tractable. Power Ledger’s marketplaces for such exchange include C6 and C6+. A really nice feature is next to your transactions, you receive alert notifications showing you where you could save money on items you actually spend money on – as opposed to irrelevant coupons on things you don’t want or need.

The Charmast Mini Power Bank is a great little option if you’re looking for a small but powerful boost of juice. It also has the added bonus of a built-in output port, meaning you can plug the power bank directly into your phone without the need for cables.However, overall, it’s an affordable and neat little piece of kit, and as long as you ensure that your phone is compatible, it’s bound to meet all your needs while out and about. There is another caveat here in that the Belkin 20K isn’t capable of charging your USB-C Macbook or other large devices with bigger batteries. Still, if you’re just looking for something to juice your phone or headphones on the go, this is a solid option.

We all know how frustrating it is when your phone runs out of battery and it always seems to be right at the point when it is most needed! Well, thanks to the new Power Wallet, this regular occurrence can now be resolved.

The 5,000mAh capacity should in theory be able to charge your phone 1.5 to two times over, but wireless charging isn’t an exact science and often loses some of the power along the way. To guarantee a full charge, you’re better off using the 622 MagGo’s USB-C port and reserving the wireless functionality for top-up throughout the day. It’s also worth noting that you can’t simultaneously charge the power bank and your device either, which may be a deal breaker for you. We strive to maintain the highest levels of editorial integrity by rigorous research and independent analysis. Our goal is to make it easy for you to compare financial products by having access to relevant and accurate information. Plus, Power Wallet has its own PowerCard rewards program to help you save even more on goods and services you want. There are two different versions of the Charmast Mini Power Bank, with either an Android-compatible USB-C or a lightning output for those with an iPhone 14 or older. We’re not sure how much longer Charmast is going to continue to produce the alternatives, with Apple famously making the leap to USB-C with the iPhone 15 series, but for now, you have to choose between the two. So, if you need a power bank for sharing in an Android and iPhone household, this might not be the one. Three of the primary projects from Power Ledger include VPP 2.0 for the sale of excess battery capacity, xGrid energy from solar panels, and uGrid — a market for commercial building solar power spare capacity.
