Lightning is a proprietary Apple technology and it used to be difficult to find power banks with a Lightning cable or charging port. Thankfully, those days are over and dozens of excellent power banks exist for iPhone users. If you picked up an iPhone 12 or iPhone 13 series phone and were surprised by the lack of a charger, see our article on charging your iPhone.
Keeping track of cords can become a nuisance. A wireless power bank works by simply resting the back of your phone on top, and letting your battery charge. Before you get a wireless power bank, be sure your device is compatible with this type of charger.
For example, the iPhone 11 battery has a 3,110mAh capacity. If the battery is flat and you charge it with a full 7,000mAh power bank, the power bank can charge the iPhone three times with 780mAh (7,000 – 3110*2=780mAh) remaining.
Device Depletion This is the state of the battery in the device you wish to charge. The lower its power, the more a Power Bank has to work to bring it back to life. We consider charging from 20% to 90% a full charge, as the efficiency loss increases beyond these points, leading to wasted charging potential. Going from 5% to 100% can take exponentially more power.
Damaged or recalled batteries and battery-powered devices, which are likely to create sparks or generate a dangerous evolution of heat must not be carried aboard an aircraft (e.g. carry-on or checked baggage) unless the damaged or recalled battery has been removed, or otherwise made safe. The airline may offer further public guidance on transporting individual recalled products.
Block power banks are one of the most common types of portable chargers. The blocks can come in the shape of a slim rectangle, a log, or a wider rectangle. This type of power bank is great for keeping in your bag or backpack for those moments when you need some extra juice on-the-go.
