Finding the right charger capacity: You'll often see a four to five-digit number, with the letters mAh following it, and that's your first big indicator of how much this charger is right for you. If you're constantly refueling your phone and other gadgets, go for at least 10,000mAh. For each extra device you charge, add at least 5,000 to the mAh rating you're looking for. Just need to prevent your device from hitting 0 on late nights out? You'll be good with something in the under 5,000 mAh rating, provided you remember to charge it often. The QiSa Solar Charger can use the sun to recharge itself, supports both wired and wireless charging, and even has a built-in flashlight. Best of all, it offers a massive 38,800mAh capacity. Who It's For One advantage of this shift to USB-C is that power banks now support USB PD for faster charging. This means your power bank will often recharge faster when connected to a suitable fast charger, at anywhere from 20W to 60W. At those speeds, even a high-capacity charger can recharge fully in three to four hours. Yes and no. Most technically deliver on the mAh (milliamp hours) they promise, but that’s not the full story when charging devices. That’s because the batteries inside a power bank are 3.7v, while USB (which is used to charge your devices) runs at 5v. Since mAh is related to voltage, mAh changes when the voltage does.

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. But if you keep a battery-powered portable charger handy, all those situations are in the past. At the price of Rs 1,999, the Realme Dart Charge power bank will not win any prizes for its capacity. However, its charging speeds are currently unparalleled, even without considering the price. If you use a supported device, it’s a no-brainer.

This feature requires a compatible USB-C cable to work. Some models with power delivery have been among the fastest we've tested, but some models without are just as fast. What else should I look out for when buying a power bank? Meanwhile, a 10,000mAh battery can give today’s flagships two full charges. A 20,000mAh battery can charge a flagship four times, or two phones two times. Some power banks have enough juice to power laptops. Of course, a higher capacity often translates to a heavier, larger, and more expensive battery. Read the Instructions: Take a few minutes to read the user manual that comes with your power bank. Familiarize yourself with its features, usage instructions, and safety precautions. This will help you make the most of your new gadget while keeping yourself and your devices safe.

In the end, it’s best to assess your typical needs before buying. If your phone hits the red zone by mid-afternoon and you only need enough juice to get you to the end of the workday, a 5,000mAh battery should be plenty. The use of USB-C for the single input/output port is a little weird given the target market, and you’ll need a fast USB-C charger and a USB-C to Lightning cable to make the most of the device.

Power delivery, or 'PD', is one of several fast charge technologies, designed to speed up the time it takes for your power bank to charge your devices. It does this by increasing the wattage used to charge to the maximum amount your device can safely handle. This only works with compatible USB-C cables, which have specialised chips that prevent overheating.
