A battery pack or a power bank with a higher capacity than usual enables you to charge your device multiple times on a single charge. Such power banks come in handy when you travel, as you might not find a power source to charge gadgets such as your smartphone, tablets or a wearable device. If you are looking for such a power bank, we have curated a list of four such high-efficiency battery packs that are available on Amazon. Note that all these products have been selected based on their listed features.
This is a budget-friendly power bank from Anker that comes with a 20000mAh battery, which should be able to charge a Samsung Galaxy S10 five times, as per company claims. It uses technologies like Power IQ and Voltage Boost to charge the connected devices quickly, as claimed by the brand. However, it does not support Qualcomm Quick Charge. It has LED indicators to give you an idea about the power left in them.
