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)

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.

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

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!

Charges multiple devices on a single charge, works fantastic in conjunction with their solar panel. The caps are sealed so you don't have to worry about water getting in, buttons are good quality and haven't broken like some cheaper battery packs do. Would purchase again

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.

Purchased along with a 14W foldable panel from the same brand. I was blown away by the fact that the little 14W panel was able to keep this battery and my cell phone charged for 2 weeks straight while it sat indoors in a southern facing window with partial sunlight.The pair exceeded expectations on cloudy days.That said, I made a mistake. While the battery had no issues in my tests, there are a few shortcomings. Sometimes it doesn't turn on. Sometimes it doesn't turn off. While the on/off feature is pretty good for the target audience, I twice in the next week noticed it stay on and discharge itself with nothing plugged in.Second, the "in" vs "out" port are virtually identical from the standpoint of, say, a camper alone in the dark at night. I am adding some GlowInTheDark orings to the neck of the OUT port, and sharpie marking instructions on the case.Third, the on/off button, and the IN port are getting strips of GID tape as arrows to them.During a power outage (extended) I directed someone to use this to charge their phones. Having verified it CAN keep a phone on for days, even without sun, I assumed all would be well. They were pre-modifications-unable to get the battery functional, and in the process managed to completely discharge it, AND were unable to recharge it from a generator.I'm buying a second one, and one of their smaller ones; but all are going to get marked up and everyone trained on how to use them.

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!

So far I love it..rugged, thought, charges fast, still very new for me so holds harge very well..I'll give further updates a year or so from now
