[REVIEW] Motorola P4000 Portable Power Pack

Motorola P4000 Battery Pack

Motorola P4000 Battery Pack

Something that has been getting wildly popular in the past couple years as the presence of tablets and smartphones has grown is external battery packs. A few years ago, when they were first starting to show up on the market, I didn’t really think too much of them because I didn’t really have many devices dependent on USB charging. Fast forward a few years, and these are super handy little external battery packs that more and more people can get tons of use from!

What’s so great about the Motorola P4000 Battery Pack compared to the numerous other options out there?

One of the best things about this battery pack is the fact that it has a micro USB cable built into the unit itself!

If you’re using this battery pack to charge an apple device, you’ll still need to supply your own cable, of course. But if you’re charging a Kindle, an Android device, or any other device that charges with a micro USB port on it.

Because the battery pack contains 4000mAh, it’s roughly enough battery power to charge your phone about 2 times, depending on how large your phone battery is. The size of this pack is also great (about the width, length, and height  of an iPhone 5). It’s easy to toss in a bag for a camping or biking trip when you know you won’t have access to power all day or during the night so you can still have a fully charged device for your trip!

The front of the battery pack also has a light-up power meter to show how much power is left in the pack (in increments of 25%).

Since there is a built in micro-USB charger AND a USB port, you could charge two devices at one time with this charger. (and YES, you can also charge the battery pack at the same time you’re charging a device with it!).

What could be improved?

I’m extremely happy with this battery pack. Most other external battery packs have two USB ports, but since this one has a built in cable and a USB port, that isn’t really an issue for me. It may, however, be an issue if you buy a pack like this hoping to charge 2 apple devices at the same time. Other than that, I really like the size of this battery and the stowable micro-USB cable. It also has an automatic on/off feature, so it won’t continue to run down the battery after your phone is fully charged from it.

The output of this pack is 1.5 amps — which is sufficient for most phones, but if you have a larger phone like a Galaxy Note or a tablet, you might want to look elsewhere to find something with a stronger output.

I rate the Motorola P4000 Portable Power Pack 5 out of 5 Stars for its great design and ease of use!


You can find this battery pack on Amazon, Verizon.com, or on Motorola’s website.

Expect to pay between $25 – $80, depending on which retailer you choose!

  1. Hi there just wanted to give you a quick heads up and let you
    know a few of the pictures aren’t loading properly. I’m not sure
    why but I think its a linking issue. I’ve
    tried it in two different internet browsers and both show
    the same outcome.
