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 far no complaints! Can fully charge my laptop @ 65W and my phone is a breeze (although it maxes out at 20V and my phone uses 21V). It is rather heavy and on the larger side, so take that into consideration, but otherwise has a super solid build and enough ports for my usage.

Can't confirm the 100w output, but I measured 162wh at 5v 1A (84% efficiency). Pass through works. Only issue is no low power mode, it will cut off in 30s if the load is less than 0.5A.

The battery pack is being used for a camera setup. It is quite effective and having lifepo4 batteries does give it quite a bit more longevity. It does charge at the full 200 watts (100 watt x 2), however this only occurs briefly before it slows to 100 and 60 watts on the charge ports. Do note that if you are charging and pulling from a different slot on the same side, you will be limited to 9 watts in each direction on that side.Additionally, DO NOT OVERDRAW FROM THIS POWER BANK. I plugged a device that tends to use 103 watts from a usb c port, and it has essentially damaged the battery from that port.A weird quirk is that if you use this as a battery buffer for usb c, it seems to occasionally stop charging and the battery gets confused on the charge state. This means that it will show as 100% full, but essentially be drained to 0% and the device and battery will shut off. Other times, it will rapidly charge from 0% to full charge, however the battery will still at 0%. Typically this requires disconnecting all devices and then connecting two full 100 watt charge connectors to the usb c ports. This typically resolves the problem for a few days.Another weird quirk is if a dual ideal diode is used to connect two of these battery packs together, this will somehow feedback power into the battery and significantly impact the charging speed. It seems to create some form of mild short, which the batteries definitely do not like.Granted all of these are problems that only occur when using the battery as a buffer 100% of the time, however that is the best use case for these batteries as they are significantly heavier than Li-Ion batteries while also being larger.

good quality , a little bulky

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.

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,,
