    Great slim design, bulging is out of warranty

    The battery pack is slim, however it has started to bulge after 2 months of ownership... which is not covered under the Energizer warranty as it falls under their "over charging " clause. Not ideal for charging the Switch as the battery pack drains quickly.

    Best Portable Charger I ever had

    This is the best portable charger I ever had, much better than all the ones I've bought from Amazon. It's a lot more expensive, but very worth it. I used this while camping outside of Best Buy for a graphics card, it definitely came in handy.

    This weighs about 30% more than stated on Best Buy's website. Normally I wouldn't mind, but I wanted to use it for backpacking, and every ounce counts.

    Very pleased with this. It is a brick, know that. But they basically all are at this capacity. I got it specifically for my oculus quest. It doubled as a counter balance. I have yet to actually play long enough to run out the battery.
