This charger is big and heavy. I needed one for my trip!! It was a bit much for me to take around while I was out and about. I like to be hands free as I explore new places and things. I was able to charge my phone 3 times and a portable fan before charging it. In my opinion this isn't to take out with you everyday unless you don't mind the weight and you have a big purse or backpack. I found myself leaving it in the room verses having it on me which defeats the purpose. This is a great charge and its a really good price. I would buy the brand again probably not as big though.

This is the “real deal” big battery; physically big, yes (comes with an attached carry strap!), but holds the most power you’ll find on Amazon for under $100. By the time you factor in the electrical loss inherent with lithium ion USB power banks, I’d estimate this power bank at around 50000-55000 true mAh’s. I tried several Icheaper) in the 50000mAh-60000mAh range before this one, and they were all inferior—I mean much, much more power loss than what should be expected for their mAh rating (like 15000mAh actual power when rated at 50000!) I returned them all, and kept and ordered another of this LOHAO 70000 bank. My use for them is to run 2 USB powered mini fans in my very small greenhouse, at night, to circulate heat from a small heater. The others (50000mAh-60000mAh) would run the fans for 8-12 hours before running out of power. BUT, this LOHAO 70000mAh bank can run them for 15 hours with 38% power left in the morning/early afternoon. Winner! I’ve also watched it closely, and it very consistently uses 7% of its power source per hour to run my 2 fans. The other banks I tried were much more all over the map, inconsistent, with the percentage of power draw to run my fans. As I mentioned this bank is large, but not overly heavy (just under 2lbs.) it arrived with a 77% charge level, but with the specified 18W charging system, it took 12 hours to fully charge (to add the extra 23%) to come to 100% fully charged, which made me nervous—that was a long time! But since that first initial slow charge, it charges noticeably faster to my relief. To fully charge from empty you’re talking about16 hours; which isn’t bad for this large of a battery with an 18W input. Quite pleased with the build quality and the reliable performance! Highly recommend! Read more

Love this backup, lasts a very long time. Long enough to run digital telescopes off of, it’s heavy but it’s worth it. Great quality, it’s not too expensive. Fast charging if using USBC port. Read more

bought it 6 weeks ago. At first it was doing well but now only charges 5050mah phone 5-6 times, also now power bank is charged much faster then before, I guess it has low quality battery cells and already degrading. Read more

Bought this as a gift, and I have no complaints, the battery is pretty heavy but provides ample amount for multiple charges on several different devices. The led display lets you know when you need to charge! Great product! Read more

It a heavy Brick. With that said. I am still testing it with my Samsung Galaxy fold 4. I am on 2 days and it's still at 68% of charge, and it charged and maintains my charge on the phone. If you are doing a long Stream on the road or a parage or protest. This Battery brick is for you. I do believe it is 70k mah. It does take 8 hours to recharge though. So, if you use it, i would see about keeping it charged. because the recharge time is about 8 hours at 68% for the price, thus far its worth it. Read more

This power supply battery is a serious workhorse. It’s heavy, yes, but that weight comes with massive capacity and impressive charge retention when idle. I use it to power external devices on my camera rig, including a lens heating sleeve and a body cooler, and it handles everything flawlessly. It’s also great for topping off phones while traveling. Just be aware: due to its high capacity, it’s not allowed on flights Read more
