Does it support pass-through charging? I couldn't find this information in the specifications.

Yeah, I have it on a monthly subscription so I can charge all my cell phones for free once a month. Me and Amazon are on the 17th charge cycle currently.

Not in CT. Our electric rates are 1 of the worst in the country.

I bought this last time it was on sale and I really like it. The description states that USB-C 1 has a maximum of 45 W output, I can confirm that this is only true when using both USB ports, if you are using only USB-C port 1, you will get the full 65W output. I use this almost every day for my Dell Inspiron laptop that requires 65W and it works fine.

The only con that I have is that it takes a few hours to charge the actual power bank. But if fast charging is not a must for you, this is an incredible deal and a great value.

Just a few hours to charge 24k power bank is a con? Do you have another similar size one that can charge much faster?

Also, I am not sure if $35 for 65w 24k is all that "incredible". Maybe if it was smaller and lighter.

If you're talking about it charging the device and also the battery pack at the same time. I don't know of any that do that

I have this and it's a beast. Just used it on vacation and kept all of us charged. 7 hours flight I kept me and my son plugged in the whole flight and it still has two bars left (s24 ultra iPhone 13) I paid $70 two years ago

The 737 can charge at 140W speeds, you can go from 0-100% in less than an hour.

For me it's overkill, but I am sure many users would find a benefit in the higher wattage.

I believe that the 537 is a great deal. You cannot find another power bank with these specs from a brand name at this price point.

I have a older one of these, a Anker 20,000mAh, that has served me well for 4+ years now. Think it's finally time to upgrade. Thanks.
