Power bank buying advice

Written by Daniel Carraway

Power bank chargers are an outdoor must-have backup for times when you get stuck without power or just need more charge for your mobile devices. When you are off the grid, or in an emergency situation, you don’t want to be without your cell phone, GPS, radio, mobile camera and/or other mobile devices. Having the best power bank charger at your side can make all the difference in the world.

Before you decide on which power bank charger to purchase, here is a quick breakdown of what these external chargers really are, how they work and the best chargers on the market today.

What Is A Power Bank Charger?

Power bank chargers are mobile battery chargers that use a standard USB plug to charge a wide range of electronic devices. Take them anywhere you go! They are all portable, and you can simply re-charge them when you get back home. Most of them plug into a wall outlet or your car’s cigarette lighter, and some are even solar re-chargeable – making them a perfect outdoor companion.

They are compatible with any device that uses a standard USB port and many of them also come equipped with a female port for a cell phone charger (compatible with most phones). All you have to do is keep them charged, toss them in your travel bag or backpack, and some of them even slip into your pocket. No fuss, no worries – off you go!

Don’t head out for an overnight trip in your tent or anywhere off the grid without one of these external battery packs. Always keep one inside your overnight pack, and of course in any emergency kit you have so you’ll never run out of juice when you need it most. At such a low price point, you can’t afford to be without one.

What Type of Power Bank Charger Do I Need?

There are power bank chargers available that include more than one USB port, and they are made with many different wattages and mAh capacity so that they can handle output for all of your devices including phones, music players, digital cameras, GPS devices, tablets and more.

For charging smaller devices like cell phones, only about 1 Amp is needed to keep them powered up. However, if you have tablets or GPS systems, you may need 2.1-2.4 Amp or higher output to charge them fully.

Power bank for charging

Consider that all of the best external battery pack capacity is rated in milliamps (mAh). Most electronic devices you’ll want to charge in the outdoors or traveling to and from wilderness destinations will be compatible as they use the same amplification rating system. For example, if you have a 2,000 mAh backupand you want to charge an iPhone, they have a battery capacity of 1420-1800 (this excludes the newest version).

Since your power bank charger has a 2,000 mAh, the most you would need is 1800 to charge the iPhone to capacity.

To ensure you have the best external battery pack that will fully charge your device, check to see how many mAh (milliamps) the device’s battery is. Then you will know if your backup charger is capable of meeting your specific needs.

**NOTE** If you decide to purchase a backup power bank charger with more than one USB port, be advised that each port will distribute mAh evenly to each device plugged into it. That means that you will need to verify the mAh output to ensure it is capable of charging all of the attached devices fully, if you are expecting a full re-charge (100%).

Allpowers output power bank charger

Here is an example of what some portable devices need:

  • iPhone 4: 1420 mAh
  • iPhone 5: 1560 mAh
  • iPhone 6: 1800 mAh
  • iPhone 6+: 3000 mAh
  • Galaxy S5: 2800 mAh
  • iPad Mini (3rd Gen): 12000 mAh
  • GoPro Hero4: 1160 mAh

If you are wondering what type of power bank charger works best for your needs, consider these three basic categories of mobile chargers:

  1. Low Capacity. Enough mAh to charge most cell phones fully.
  2. Mid-Range Capacity. Enough mAh to charge more than one phone fully, or your own cell phone 2-3 times.
  3. High Capacity. Enough mAh to fully (or almost fully) charge a tablet, small GPS system and some digital cameras.

    I have EC Technology power bank, and love the fact it’s 22400mAh, but keep in mind it’s heavy and bulky.
    It’s good at charging phones and tables, and it can hold a charge for quite some time. The flashlight function is okay, and I am sure in an emergency would be great, but it’s not that bright, and it doesn’t cast well.

  • Daniel Carraway

    The higher the charging capacity of power banks, the heavier they get. Although I think in time, they’ll figure out how to make these sleeker and lighter. Even if they can be a bit chunky, they do a marvelous job of charging all our gadgets, right? Very useful especially when you’re camping or traveling. They are also affordable, too.

  • Joe McGowan

    Having bought a number of Anker products in the past, I was initially drawn to this charger simply because of the name. The small size was also a big plus for me as I didn’t want to have to carry a big, bulky charger around with me. Conveniently, it fits in my pocket along with my phone. I’ve only used the charger to charge my iPhone 6 so I can’t comment on how well it detects other devices but for the iPhone 6, at least, the charging capabilities are top notch, especially when considering the size of the charger.

  • Mark Foster

    I say, it works on all gadgets and it’s quite handy and compact. Remember, though that the higher the mAh of the power bank, the bulkier it will be. Although I believe that in the coming years and with the new technology coming, these plump babies will shrink – and I’ll be the first to be celebrate!
