Great Power Bank for the price!
Pros-When the power bank is fully charged it can charge 4 to 5 phones from 0% to100% much faster than what your wall plug can do. Worth the price. I use it for camping and it doesn’t let me down.Cons-The product is pretty big and bulky. Takes almost 24hrs to charge the power pack from 0% to 100%

Not anywhere near the advertised 40000mAh capacity
Long story short, when testing this out it has potentially only 1/4 the capacity that they advertise. See below for the details.My iPhone 14 Pro Max has a battery capacity of 4,323mAh. This power bank supposedly has a 40000mAh capacity, which is the reason I bought it. Being able to charge my phone nearly 10 times off this thing could come in incredibly handy in an emergency.So I bought this a few months ago and tested it out and while the math didn’t seem to add up, I knew I’d still get a couple full phone charges out of it so I didn’t bother complaining, as I didn’t have any other power block and it was certainly still useful.A few days ago I decided to get another power block with a bit higher wattage, even if it was rated a smaller battery (25800mAh). Today I tested the two of them together.Both power blocks were topped off at 100%. I used an app to drain my iPhone battery down to 80% and then plugged in one of the blocks and charged it to 100%, then did the same for the other block. I compared the time it took to charge the phone from 80% to 100% and how much juice was left on the power block afterwards. I closed out all my apps and had the same functions off/on, same brightness on my phone etc. and didn’t use my phone at all during the tests. Here are the results:-“40000mAh”, 30W power block (the product you’re looking at): Took about 85 mins to charge my iPhone 14 Pro Max from 80% to 100%, and had 92% left in the block down from 100%. That means you’d use up about 40% of the power block charging my phone one time from 0% to 100%.-25800mAh, 65W power block (the competitor): Also took about 85 minutes to charge my phone from 80% to 100%, and had 91% left on the block down from 100%.Summary: The charge time was the same on both, and was done with a USB-A to lightning cable. My phone’s battery, again, is only 4,323mAh. So in a perfect environment (which I’m aware this wasn’t) charging 20% of that capacity means 864.6mAh was used, which brought the power block to 92%. That means the capacity on this power block you’re considering would be around 10808mAh, or roughly 1/4 what it’s advertised as. The other power block which is advertised as just over half the capacity of this one was nearly identical in power usage (1% off). The competitor still didn’t add up to the advertised 25800mAh it had, but of course there may be other factors at play that impacted both tests (maybe the last “20%” of a phone charge uses a disproportionate amount of power, my phone was still on and technically using power as it was charging, etc.)Even if you don’t trust my admittedly barely scientific math in this quick test (which is understandable), the fact remains that a power bank advertised as 40000mAh only actually has roughly the same capacity as another power bank advertised as 25800mAh.Now, the other power block I got is valued at twice as much as this one, so in that respect this is still a value. In the end the price is still good on this product, just make sure you’re ok with not having anywhere near the advertised capacity. My star rating reflects the suspected false advertising of capacity from the seller.**updated review**Add not being able to survive one 3 ft drop to the review. I accidentally dropped this off my desk, and now it’s rattling and nothing you plug into any of the ports charges.

Exactly as described!
