On the right side the display shows battery charge remaining at the top, which is totally unreadable but the color will change when it gets low. Then you have total cell voltage, cell current, and two temperatures which I believe are the circuit board and cell temps, and finally a timer showing how long power has been drawn from the batteries. The magnetic wireless charging plate uses the same aluminum finish and glass cover that reveals the charging coils and magnets. A power delivery port along the bottom lets you connect any USB-C cable to the wireless charger (including a USB-C to USB-A cable if your car doesn’t have USB-C). Momax even includes a power toggle on the charging plate, so you can optionally use the MagSafe accessory as a phone mount without always charging. Power banks above 20k mAh start to get fairly heavy and less portable, but they’re great for folks looking to charge a larger device such as a laptop on the go. If you’re searching for a bank that can handle the demands of laptop charging, around 20k mAh is the bare minimum capacity you should consider. On this list, the Goal Zero Sherp a has an impressive capacity of 25,600 mAh. The Lion Trek is another excellent high-capacity power bank — and it even sports a standard three-prong AC outlet. Charge Times and ‘Fast Charging’ If you charge a pair of earbuds with a superpowered fast-charging wall port or power bank, it can cause irreversible damage to the battery life of those headphones. Many modern power banks — such as the OKZU C10002Y and the OtterBox Fast Charge — can decrease their output to meet the needs of a small device or fragile battery.

Editor’s Note: In November 2023, we updated this article to provide additional information on how we tested and evaluated power banks.

Wireless Charging and Magnetic Power Banks In 2023, nearly every gadget and gizmo that we use has a battery. Our phones are the primary example, but nearly everything — from headlamps to headphones — has built-in rechargeable batteries.The USB-C version is a great fit for iPhone users who already use USB-C accessories (Momax includes a USB-C to USB-C charging cable in the box) or need the fastest charging options in a pinch. Both power banks feature 5000mAh batteries, but this version is capable of delivering power faster as an option. Just consider the tradeoff in convenience of charging the power bank with the same cable as your iPhone (at least until next year when the iPhone 15 is expected to switch to USB-C). Magnetic Wireless Charger and Car Charger

Nearly all small electronic devices including smartphones, smartwatches, tablets, earbuds, headphones, and laptops charge via one of three standard input ports: Micro USB, USB-A, and USB-C.Our durability test involved prolonged regular use indoors and out, and a standardized drop test. Every bank was dropped exactly 2 feet onto a concrete surface to simulate the classic electronics fumble that we all experience from time to time.
