RAVPower 20100 mAh External Battery Review

As phone manufacturers move further away from removable batteries, external battery packs have emerged as an alternative for users that need to top up on the go. Overall, they’re typically a better value: replacement batteries run about $40, while external batteries can start even cheaper for lower capacities. Spend a little bit more money, and you can get a battery pack good for multiple charges. Unlike a second battery for your phone, battery packs can be used for multiple devices and can be kept even after upgrading.

The ports. The USB-C port can be used for both input and output.

A few months ago, I purchased the RAVPower 20100mAh External Battery. It’s a simple black box with a few ports, and 4 LED lights and a button to indicate how charged the pack is. Press the button, and the lights will show 25, 50, 75 or 100 percent of charge. The four ports are Micro-USB for input, USB-C for both input and output and two full sized USB ports for output. One full port is able to output quick charge, while the other is for older devices not compatible with quick charge. The battery pack can be charged itself via quick charge in both the Micro-USB and USB-C ports.

I use the battery pack with my Nexus 6P and Nvidia SHIELD Tablet, and even on heavier weeks where I’m doing a lot of travelling, it’s always been reliable. The pack is good for five and a half charges of the Nexus 6P, so I haven’t run into a situation where both my phone and the battery pack are dead. Being able to quick charge the battery pack with the same exact charger is a bonus convenience. Though there’s no way of knowing the exact charge at any time, I haven’t noticed any issues with the pack losing charge when it’s sitting idle.

The pack is almost the size of a new Nintendo 3DS XL. Same thickness, a little longer and a little more narrow, but close. It’s pretty easy to fit the pack in my back pocket if need be, though I prefer having it in my backpack. I haven’t done anything too crazy with the pack, but it’s survived a few drops onto concrete without a scratch. I’m not going to push the limits of its rigidity (because batteries go boom), but it should hold up well in a carry on bag while traveling.

Throwback to the 80's

I purchased the RAVPower 20100mAh for $65 on Amazon, but it’s currently down to $55. At either price, it’s a worthwhile investment for a battery to charge all your devices for years to come.
