60000mAh Power Bank,Gifts for Men,200W Portable Charger with 2 Fast Charging USB-C &2 USB-A Output,Compatible with Phones Airpods Laptop Drone for Home Backup Travel Camping Essentials

So this is the most impressive large USB battery bank I've seen or used. When I read the product description I initially thought they had to be lying about some of the specs. This is a large battery bank, it's a little smaller than a nalgene bottle. This is not the battery you bring out and about to top off your phone once during the day. It's heavy, weighing in at 1.4kg (3 lbs). This is the first portable USB battery I've seen that uses lithium iron phosphate cells. It has worse energy density compared to other lithium ion batteries, but it's much safer!So they advertise this battery as 70 Ah. That spec is at 3.2V though, not the typical 3.7V for other lithium chemistries. What's more useful is the total watt hour rating. This is labeled as 192 Watt hours. I measured 212 watt hours of charging to take the battery from empty to full. I also measured 173 watt hours of usable capacity where the battery charged my macbook pro before dying. That's an astounding 90% efficiency. Most other USB battery banks I've tested usually come in at 60-65% efficiency. You buy a 10 amp hour battery and only get 6 amp hours of usable capacity.Then there's the charging speed. I measured a true 200 watts of power going into the battery using 2 separate 100 watt chargers simultaneously. Absolutely nuts.I expect the electronics to die before the cells die. LiFePO4 cells have a very high service life compared to other chemistries. The top of the battery does get a little warm while charging at 200 watts. Get this battery if you need a large capacity (173 watt hours) USB PD power. Also it does support PPS charging if you cared to fast charge your Samsung phone.

This is a fundamentally sound charger that provides exceptionally high capacity for the price. It does have a couple of small issues:1. You cannot tell if it's charged 100%, but I got a USB cable that shows the wattage, so I can easily tell when it hits 0 watts.2. It is only charging at 49w from the ZOUPW solar panel. This is a limitation of the USB output from the solar panel, however.It is very solidly made and uses LiFePO4 batteries, which will provide at least a decade of use. I can't find another power bank anywhere near this price that uses LiFePO4 batteries and has this much capacity.

Works great with excellent capacity. Just not enough output ports for my use.

It's big, it's heavy, but it's SAFE. For those in the know, this is a special battery pack, but because of it's chemical composition (LiFePO4) it can't overheat or explode. If you've seen lipo or li-ion batteries catch fire because they've been used too long, or they bend the wrong way, or it gets a little too hot or the battery gets slightly damaged, you'll know it's not safe for intensive use. So yep, until another product comes with this chemical composition that is lighter (unlikely because the weight is chemically determined) and/or better in another way, this is it.

I hate to leave a negative review and I really wanted to like this, but this keeps shutting off every time I plug my phone and another USB device. will not charge 2 at the same time. also it keeps restarting for no reasons.. SorryUpdate.. They reached out and fixed the issue in the same day.. sending replacement and this unit works like a dream.. Thanks so very much.. AS ADVERTISED and MORE!!! Will buy more in the future,,

Looking everywhere on amazon this is the equivilant of a med portable speaker that you can trust to last to charge electronics. Charge lasts long and it charges as fast as an outlet. Had to edit. No reason for the 4 star review a person wrote below why need a digital screen more tech more problems prone to faults.... will charge my s23 ultra 4x over

Absolutely put it to the test.Great quality.Byeing 3 more.Great to have in a go bag 🎒 for emergencies

I have been looking for a good power supply box and thought this was it based on other reviews but I guess as usual I’m not the lucky one. One of my USB ports doesn’t work or charge anything and the light only stays on for about 15 seconds before shutting off. I was really looking forward to this power bank only to be let down !!!
