INIU Power Bank, 20000mAh 65W Compact USB C Laptop Portable Charger, PD QC Fast Charging 3-Output Battery Pack, Travel Charger for Laptop MacBook iPad Tablet Steam Deck iPhone 16 15 Samsung S22ClimatePartner certified

I purchased several of these to power some outdoor cameras that aren't battery powered. There were a few things I wanted to solve:* I needed a compact dual USB-C charging including at least one pass-through capable port. Passthrough charging allows you to charge up the battery pack while still powering some other device at the same time. Most power banks do not support this. This one does.* I wanted something that I could charge up quickly when needed. This also supports fast charging.* I needed a pack with both charging ports on the front or back of the unit (not on the side). Check.* I wanted something that had the highest amount of stored energy possible while being rectangular and highly compact.* I needed a bank that could handle reasonable outdoor spring/fall temperatures. Though, I didn't need it to be weather proof, since it is being used in a sheltered area.This is the most compact 20,000 mAh power bank I've been able to find to date that has pass-through charging. They've been working great for over a month now in temperatures ranging from 40 F - 87 F.I love the charging protections this has built in, which makes it much safer to use.The fast charging output allows for up to 100 W of power over USB-C.The input fast charging (charging the bank's battery) allows for up to 45 W, changing the bank from 0% to 100% in under 2 hours.There is a large power display that shows the percentage of stored battery power left. It stays on until there isn't any power draw or the battery is depleted.The rest of the power bank has a good grippy coating that means you'll be less likely to drop it.There are two USB-C ports, one allows for output only, the other allows for input and output (so you could use pass-through charging or charge a second USB-C device). There is also one USB-A port that is only for output. Each port is clearly labeled with the maximum charging output as well as whether the port allows for input or output.The construction feels solid and well-built. The ports grip firmly and don't move.So far, after about a month and a half of use, I would happily recommend this power bank to anyone who doesn't need a completely weatherproof indoor/outdoor power bank.
