How We Decided
There are so many portable phone chargers on the market, it can seem like a crapshoot when you are shopping for one. During our research, we ruled out older models that used antiquated technologies and focused on long-lasting batteries that powered devices quickly and safely. We also wanted a nice mix of pocket-friendly chargers, sacrificing some battery size, and high capacity units that were a better fit for purses or backpacks. If you want a larger portable option, take a look at the best battery box instead.
We didn’t dip below 6000 mAh on this list, which should get you two full charges on a brand new iPhone or Android and more with older smartphones. We also wanted to make sure the warranty was up to snuff, ruling out products that offered up anything less than 18 months. Finally, we took a long look at how many charges these batteries could take before needing a replacement, declining to feature anything under 400. If you want to continue using disposable batteries take a look at the best C batteries too.
Portable Phone Charger Buying Guide
The Most Important Features to Consider
As you are researching which charger to buy, consider these features and whether or not the product you are eyeing is up to snuff with industry standards.
- Battery Size and Capacity
This is the age-old query when it comes to batteries, finding the perfect size and capacity to suit your needs. Are you someone just looking to get through the workday, with a moderate amount of usage? Then take a look at the smaller capacity batteries, which will still power your phone up to three times on a single charge, while remaining both pocket and wallet-friendly. For everyday users, 6000 – 10000 mAh would be your best bet. These units are typically small and light enough to insert into your life seamlessly.Are you someone who runs their gadgets through their paces, several times over, without having access to a power outlet? One of the higher capacity batteries may be right for you, something above 20000 mAh, which will allow you to charge your phone up to eight times on a single charge. These units are often much larger, heavier and pricer than their smaller capacity cousins.No matter which you choose, however, gone are the days of dinky 3000mAh, or lower, batteries. You’ll still get multiple charges before needing to power up.
Portable phone chargers now come with a variety of both input and output ports, often allowing multiple devices to charge at once. Many chargers nowadays now come equipped to interact with newer USB-C cords, speeding up charge time considerably. All of the products on this list are compatible with standard USB cords, which adds to their universal appeal.
- Fast Charging
One thing to consider is just how fast you want your device charged. Most companies boast all kinds of proprietary tech that reportedly speed up this process but, ultimately, it boils down to voltage, amperage and wattage. Amperage refers to the current flowing from the battery to the connected device, while voltage is the amount of potential energy that can be sent. Multiplying these two numbers gets you wattage, which is the number you are looking for. The higher the wattage, the faster it’ll charge. Industry-standard is around two hours for a full charge to an iPhone or Android, though some proprietary technologies can speed this process up.There are some laws of physics at work here, but companies can boost wattage by varying voltage or amperage. Of course, your maximum charge speed can be hindered by what cords you are using and the end device itself. Ideally, for the fastest charge, you are looking for a charger, cord and powered gadget that all support the same standard, be that Samsung’s Fast Charging or some other similar tech. With this list, we erred on the side of universal support, bringing us to the question of wireless charging.
- What About Wireless Charging?
You may notice a distinct lack of wireless charging devices on this list. This was a conscious choice, as many gadgets simply do not support Qi wireless charging. In other words, we wanted to eliminate the question of “will this charger support my device.” As long as your gadget can be charged via standard or micro USB, it’ll be supported by the above products. If you are looking for wireless charging, here is a list of the best options out there.
