Buying Guide for the Best Google Portable Charger
When choosing a portable charger (also known as a power bank) for your devices, it's important to consider how and where you'll be using it. Think about the devices you want to charge, how often you'll need to recharge the power bank itself, and how portable you want it to be. Making the right choice ensures your devices stay charged when you're out and about, traveling, or in places without easy access to outlets.Capacity (mAh)Capacity is measured in milliamp hours (mAh) and tells you how much charge the portable charger can store. This is important because it determines how many times you can recharge your device before needing to recharge the power bank itself. Lower capacities (5,000–10,000 mAh) are lightweight and easy to carry, suitable for giving a smartphone one or two full charges. Mid-range capacities (10,000–20,000 mAh) can charge a phone a few times or a tablet once, making them a good balance between portability and power. Higher capacities (20,000 mAh and above) provide more charges or can handle bigger devices like tablets, but are bulkier and heavier. To choose the best one for you, consider how many devices you need to keep powered and how long you'll be away from a wall outlet.
Output Power (Amps or Watts)The output power determines how quickly your devices get charged. This is typically given in amps (A) or watts (W), sometimes as 'fast charging.' Lower outputs like 1A are slower and best for small devices like earbuds. Outputs of 2A or greater can charge phones and tablets at a reasonable speed, while even higher outputs (such as 18W or more) are ideal for fast-charging newer phones and some laptops. If you want fast charging, look for a power bank with higher output. If speed isn't important, a standard output will suffice.
Number and Type of PortsPortable chargers come with different numbers and types of charging ports, such as USB-A, USB-C, or even Lightning connectors. Having more ports allows you to charge multiple devices at once, and newer port types like USB-C can offer faster charging and are compatible with more recent devices. Think about how many devices you need to charge at once and what types of cables your gadgets use. If you only need to charge your phone, a single port may be enough, but for families or multiple devices, more ports are better.
Size and WeightSize and weight affect how portable the charger is. Smaller and lighter power banks are easier to carry in a pocket or purse, making them great for daily use or short outings. Larger chargers with more capacity are better for travel or long trips but may be too bulky for everyday carry. Decide how much you're willing to carry based on how often you'll need the extra power versus how convenient it is to bring along.
Input Charging SpeedInput charging speed tells you how fast the power bank itself can be recharged. If a charger takes a long time to refill, it may be inconvenient if you need to use it again soon. Higher input speeds (often listed in amps or as 'fast recharge') mean the power bank will be ready for use quicker after it runs out. If you often need your charger ready to go, pick one with faster input speed.
Safety FeaturesSafety features like overcharge protection, short-circuit protection, and temperature control protect both the power bank and your devices. These features are important for reliability and peace of mind, especially if you leave your charger plugged in or use it frequently. Look for chargers that mention these protections if you're concerned about safety.
