I usually will not write a review so close to purchasing a new product. However, these are superior to any battery bank I have used so far. They seem very durable, EXCEPT to fall/drops. Not sure but I think the case can withstand substantial drops but, circumstances could still cause it to be injured/destroyed Iβm certain. A ten foot drop into a concrete stairwell wonβt be good. But off the kitchen table onto the tile floor and all will be likely well. Still, if charging something and it falls, port and cord damage is possible, if not probable. However, it is to charge. Waterproof covers that thread on to secure your battery ports when not in use. But the winning feature for me is the ability to place it in βgearβ mode which servers the manufacturer the ability to produce accessories to use with your tripod mountable battery. Cool ! The gear mode for me however provides the opportunity for use with a device that only intermittently draws power. The battery powers it perfectly so my device can fulfill its purpose π I will update this in about 6 months unless it works as well as it does now. Seems durable and well made with great features at a reasonable cost. I bought 3 initially on faith and it may have worked out aces for me! Update 1: Not yet six months but these batteries are fantastic! Hold a charge very well. Additionally, one charge then use as intended lasted 10 - 8 hour shifts. Nicely done! Read more

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. Read more

Very well built, heavy duty. Took it out in a rain storm with no issues exposed in my pack. Recharged my iPhone several times and probably could have charged it a total of 5-8 times from 10% battery. Highly recommend!! Read more

This battery is built like a tank, boasting top-notch build quality. As someone who spends a lot of time outdoors, Iβm pleased to report that this battery has kept all my devices charged consistently. The waterproof seals and the overall design of the battery are commendable. It offers great overall performance and is quite compact. The only thing I wish it came with was a D ring screw, which would make it easy to attach to a carabiner and eliminate the need to purchase one separately. However, I must say that this battery is simply awesome. I held off on buying it for a while, but I should have gotten it sooner. If youβre on the move frequently and donβt have access to power sources, this battery, combined with a portable solar panel, will ensure that your devices remain charged. Read more

Yip. It is true. ELECOM is over advertising the the "capacitance" of this bank. However, the IPX rating and impact rating of this battery are, in fact, life saving and very true! Read more

This power bank is beyond amazing. If you do a lot of outdoor activities, especially ones that require you carrying gear from point A to point B, definitely pull the trigger on this one. I also purchased the solar panel to go along with it. On a bright day, this thing will charge from 0% to 100% in roughly three and a half hours. If you manage your time just right, you might be able to get it fully charged twice in a day, depending on weather and geo location. I do use a few power hungry devices on my treks, which is why I purchased the solar panel system with it. This charge block is rugged and I have dropped it a few times, but it landed in dirt and grass each time, so that probably doesn't count. It is waterproof, or at least very water resistant, as I have, on two occasions, left it outside the tent over night in the dew and ultra humid environment. I have now had this thing for eight months and it still charges the same as the day I got it. Go ahead and hit the buy button if you really want/need an ultea reliable and rugged power bank. And, get the solar panel too... both are very lightweight and add very little weight to your rig. Read more

Takes a bit to charge. EXTREMELY short charge cord. Read more

Just what I wanted! A ruggedized battery to take on camping/backpacking/hunting trips! Works great and I saves me the weight of putting a normal battery in a waterproof container. Read more
