power pack that's BUILT FOR THE WILD
We created the first portable USB-C power bank created for adventurers like you! From design to production, we built rugged durability into the very soul of our Power Packs. Now you can enjoy more efficient power delivery and faster charging for your devices in the wild.
Power up on the go with our portable and reliable power pack
Our Power Pack is designed to be rugged and durable, so they can withstand the rigors of outdoor use. A useful tool for camping, providing convenience and flexibility while on the go.
The shape is outstanding and so nice to carry. The ports indeed offer stronger and more secure connection points...
It is so useful when I’m out camping. It is small and easy to carry but has the juice to charge my phone multiple times without recharging...
Been using it as I backpack in Oregon and it’ll charge my phone up to about 50% which always helps!

Power Pack Benefits
Small But Mighty
Lightweight and compact designs. Allows you to charge your devices on the go, whether you're on a long flight, hiking, or camping.
Dust Proof, Water Resistant
Our USB-C ports are fully waterproof giving you extra security and confidence when you’re using this in the wild.
Carrying our Power Packs are actually comfortable, we ditched the hard edges and created rolling edges and an ergonomic curve so that slipping the Power Pack into your Ember, Hot Pocket, or pants pocket feels great.
Our ports have a physical connection point that syncs with our plugs, reinforcing the connection and increasing durability. No more connection breaks.

I had this UL battery when I got a Hot Pocket, but exchanged it for the larger XL since I wanted longer than 6 hours for overnight warmth. The XL is fabulous, delivers all the power I need, but is quite heavy, and noticeably so in the low back battery pocket on my Ember pullover (I'm a petite lady!). Finally caved and ordered this smaller battery for that use, and tried it out last weekend. It's perfect!! I don't notice the minimal weight or bulk, and it gave me a solid 6 hour window of use on both high and low heat settings. Now I'll need to think about which battery I need for the day, but it sure is wonderful to have this option!!!
Thank you so much for the time and effort to send us this review with a 5-star rating, Vicki. It means the world to us. Thank you for supporting Sierra Madre! :)
I like the size and shape of this battery. Yet to see how long it lasts. Am using it interchangeably with the Pocket, the lights for the hammock and my Ember jacket which I adore!!! I have a second battery so I always have one charged. Great on the airplane for all my gadgets!
Glad that you like it. Thank you for taking time and effort to write us a review, Laura. It means so much to us. ENJOY!!!
Been using it as I backpack in Oregon and it’ll charge my phone up to about 50% which always helps! It charges the phone super quick but takes a few hours with the solar base and one link to charge the pack itself
So glad that it charge your phone well. Thank you for supporting the Sierra Madre, Critter.
The UL powerpac, obliterates the competition, with outstanding versatility. The output heats the Hot Pocket faster than I had contemplated. The availability of higher output is great for charging devices that require higher wattage. The shape is outstanding and so nice to carry. The ports indeed offer stronger and more secure connection points. The wait was well worth it! Thanks for great support as well. My Wife loves her Hot Pocket as a lap robe for early morning warmup! Quick, easy and long lasting!
Thanks for the feedback! Love seeing that this worked out great for you Rick!
