What Our Gearhead® Experts Are Saying:
"BaseCharge 1500+ has become my camp HQ. I can run lights, recharge camera batteries, and top off e-bikes without firing up a loud, fume-y generator. The display takes the guesswork out of power planning, and pass-through charging plus solar input keeps me topped off during multi-day basecamps."
When the trailhead becomes our basecamp, the BioLite BaseCharge 1500+ brings dependable, whisper-quiet power. We keep fridges humming, lights glowing, and gadgets charged without fumes or noise.
A robust inverter, multiple AC and DC ports, fast USB-C PD, and an intuitive power readout make it simple to plan our energy for the trip. Pair it with solar for a clean, off-grid setup that scales from weekend campouts to cabin backup.

Deep Comfort
[This review was collected as part of a promotion.] Ok so I went and splurged on a nice sleeping bag. Why? A good bag will last about 10 or more years in my experience. This was definitely an upgrade, nice features and super fluffy. It doesnt pack down as much as I thought it would but my days of ultralight long distance hiking are over and this is a perfect option. No regrets.

LOVING this Sleeping Bag; Bought Used in Excellent Condition
[This review was collected as part of a promotion.] I bought this for future, unknown trips. My nephew immediately took it out of the box and got into it. He looked so comfy I decided to try it in my bed and now I just love it and sleep with it. It OPENS on the bottom to stick your feet out. This is why I bought it. I can't stand sleeping without sticking my feet out to breathe lol. So, it hasn't even made it outdoors yet but the quality and comfort is excellent. I bought it used on the site and it was in excellent condition as described. Has a very nice packing bag as well with straps. This is why outdoor equipment is worth paying a premium; you really get what you pay for and I highly recommend the brand.

The blue cocoon
[This review was collected as part of a promotion.] Great spring and summer bag! Super soft down and silky fabric. I love the zippers to vent, especially when my feet get hot, I can open the bottom and keep warm up top. High quality zippers with extra fill around them to prevent snags and drafts. Love it! Mesh storage bag is a nice addition, but it could be bigger.

This is a wonderful sleeping
[This review was collected as part of a promotion.] This is a wonderful sleeping bag to be used during cold temps. Handled single digits well. I used the reactor liner with this bag. I am very impressed with the quality and packability of this version. Would order again!

Hefty
[This review was collected as part of a promotion.] This sleeping bag was super easy to set up. Felt like I was in a cocoon throughout the night. Wish breathability was better. Idk how butterflies survive if thats what it feels like!

Side sleeper in sleep heaven
[This review was collected as part of a promotion.] I love this sleeping bag. I am a side sleeper who likes their feet out. This bag meets these needs and goes with me everywhere I go. I sleep on my left side, the men's version is the way for me.

Amazing
[This review was collected as part of a promotion.] This is a very durable sleeping bag. It also helps keep your body temperature regulated so you’re not cold or super hot. I love the versatility of it and the packability of it.

Warmth and comfort
[This review was collected as part of a promotion.] This is warm! It’s down filled. Can accommodate a person up to six feet. You can hook 2 sleeping bags together to make a double sleeper. Light weight. Not as constricting as some other mummy bags. Definitely a great find.

Good quality sleeping bag
[This review was collected as part of a promotion.] I can't wait to use this camping! This is a very nice quality down sleeping bag. It's comfortable and roomy and is rated to keep you warm down to 15 degrees! The down didn't poke through the fabric and the zippers worked nicely. My only issue is that one of zippers seems to need fixed as noted in one of the pictures. I like that it came with both a storage cube so the down doesn't get deflated in storage but it also has a travel bag for your trips!

Super comfy!
[This review was collected as part of a promotion.] Super comfortable sleeping bag with a really good design to keep the zipper from breaking. Warm and more comfortable than most. Beautiful color and had multiple bag sizes to choose from.
