ELECOM NESTOUT Rugged Power Bank, 15000mAh Outdoor Charger, 32W USB-C Fast Charging PD, Waterproof IP67, Durable Shockproof, Battery Pack for iPhone Tablet Hiking Travel Camping (Gray Blue, 15000mAh)

What a great quality, power bank, great boat, very rugged and charges quickly

I've needed a battery bank for taking up into the mountains on hiking trips. My usual concern is getting the power bank wet or damaged. Its an amazing change of pace to not have to worry about keeping my power bank protected. This thing can take a beating, I've dropped it countless times, it's been splashed and thrashed since I received it and it still works like it's brand new. I've even seen videos of people fully submerging theirs underwater with no issues. Worth every penny, I already plan on getting another or getting the solar charging module for hikes longer than just a weekend.The battery lasts a good long while, I've used it on several weekend trips and it usually lasts the whole time keeping all of my electronics powered and also acting as a camp lamp using the lamp attachment.My only very minor nitpick is that I wish the USB-C port side had a different texture on the cap to differentiate the two caps in low/no light conditions. I've mediated this by inscribing a texture onto the outside of one cap with an awl and writing on the outside of the body in paint marker so I can tell the difference under red light or in total darkness. I also wish that the lights themselves were able to be turned off or came with an integrated cover as there are times I don't want a bright light flashing at me (although this was easily fixed by covering the battery indicator light with a piece of electrical tape).Overall an excellent battery that deserves to be taken outdoors. Never have worry about a battery pack again once you get this.

Easily the most durable, longest lasting and unique product out there. Definitely worth purchasing to use as a backup to have in your car and home. The 15000mAh size can last a long while. It's pretty much plug-and-play. Small enough to fit in a pack and drawer, charges fast for such a big power bank, and more!

Awesome little battery pack. The one I purchased came with a light attachment which is so cool. I'm in the military so I use this when I go out to the field or whenever I'm getting 'in the dirt'. The light and the tripod are great for when it's late and I don't want to use my phone light and bother others due to the soft white adjustable nob. Nice compact size with alot of power. When charging out using, it doesn't appear to get over heated or anything. The caps that cover the ports are really great, keeps dirt or water from getting in the ports, very durable. Great idea!

Wonderful design and material build. But only four stars because I cannot get the device to do combined charging (i.e. charge itself as well as charge other items at the same time). Combined charging is stated in the english manual (see below). I may be doing something wrong. So I hope customer service will see this review, and tell me what I am doing wrong, If so, I will upgrade this review. If not, then sadly, I could not get the combined charging feature to work. This becomes relevant is using the product as a travel charger, or if camping and connecting it to solar panels.

Great little battery pack. Puts out enough power that I can use it for my Ham radio and keep my phone charged. Will definitely be ordering another one. Fits nicely into my radio bag. It’s a little to big for the pocket, but that’s ok.

Dragged the charger around Block Island and Montauk this weekend. Lots of salt water and sand. All the seals held and I had a steady supply of backup power. The real difference between this charger and other waterproof chargers I've had are the screw on seals which are sand and grit proof, both of which can be just as bad (if not worse) than water. It's a little on the heavy side for what I was doing (surf fishing), but that's not really a design flaw. I should have probably gone with the single version.

I love these. The concept and execution are great! One reminder: if you are running gear overnight (like the fan cooling you off in your camping hammock) make sure you actually turn the battery on, and don’t just plug it in and think it will run until it dies. It WILL turn off after an hour or two unless you push and hold the battery’s button so it is actually ON. I didn’t realize that was the case until 4am when I woke up sweating. I’m still giving this 5 stars because that is how it’s supposed to work. I do wish they would come up with an air pump for camp inflatables like sleeping pads and possibly for sports balls. I think those would be awesome additions to their system.
