Lots of power at a reasonable price

Darin Kellyโ€”December 30, 2025

Very good power bank with lots of power. It works very well, with two usb-a charging ports and one usb-c charging port. I like the versatility of this as some items we have still need a usb-a port and others (most now it seems) use a usb-c. I put this one through its paces and was able to use it to fully charge an iPhone 16 plus 4 times over a three day period and it got down to just below 15%. I could have used it to charge more, but I went ahead and plugged it in to recharge it and it took about 5 hours or so. I love that it gives a readout of how much power is left in percentage. It seems pretty accurate as well. It has a flashlight on it, but I doubt it will be used much, but would be good in a situation where there is no power and you need some light obviously. The big con for this one, and kind of goes with the territory when dealing with a power bank of this capacity, is size. It is a chunky beast. It is kind of heavy and wouldn't be something I'd think you'd want to carry in a pocket or purse or crossbody bag. This is definitely a backpack type item. The price is somewhat reasonable when considering the capacity of the device. I've seen power banks with less capacity selling for more. I think if you were in the market for a versatile, high capacity power bank that you'd want to keep in your car or backpack and are not worried about the size of it, this is the one for you.

Nice portable power bank

Timeโ€”December 28, 2025

This portable power bank is very well built and charges my phone quickly with power to spare. The power bank charges my Samsung S24+ fully 3 to 4 times and still has power left over, I usually recharge the power back to full after 2 or 3 phone charges so I'm not caught with a dead phone and a dead power bank. The power bank has two USB-A connections and a USB-C connections and I've used both type of USB connections to charge my phone with out any issues. The power bank is small enough to keep it in your glove box or back pack so you are never with out a phone charger. The weight is comparable to other 30000mAh power banks and is not overly heavy to carry around in your backpack. The power bank is functional as a phone charger and works as well as the factory charger but does not keep you tied to a wall outlet. The power bank comes with a flashlight to help you find the charging cable in your back pack and get it connected up in the dark. Read more

Emergencyโ€‘Ready Power Bank with 100โ€‘Meter Flashlight and Fast Recharge

S. K. Bryantโ€”December 30, 2025

The media could not be loaded. This portable charging bank is enormous and packed with enough power to keep you going when away from an electrical outlet. It would be perfect for campers or trailblazers who find themselves out in the middle of nowhere and needing to recharge their phone or other USB-connected devices. It also has a built-in flashlight. It weighs just under 1 pound, which makes it a reasonable weight to carry in a purse or backpack. An invaluable power bank that can charge three devices at once. When it runs out of juice, it can be fully recharged in only six hours! I have used portable power banks while traveling in the past. I also use them to power a small cube-sized camera to take video at family parties and events. This device is similar to older power banks, with the one significant difference being its width and weight. You can see two of my previous power banks in the photo below, compared to this one. The flashlight in this charging bank has a 100-meter range and not only lights the way but also flashes to indicate an emergency or that help is needed. I am delighted with this power bank; it has everything I may need in a variety of situations. It's definitely worth its very reasonable price. Read more

Great battery, definitely recommended!

Monroe Freedmanโ€”December 30, 2025

This is one of my favorite power banks so far. I've had quite a few over the years, and this one has served me well. The light is a very useful function on the rare occasion that I forget to throw a flashlight in my bag. The last of these that I had was dropped, and the internals shifted slightly, making the power button unusable. That said, it still wakes up and functions normally when something is plugged in. One issue that I have with this battery in particular is that the shutoff threshold is pretty low. If I leave my wireless charger plugged in, the battery will drain over time. This has not been the case with other batteries that I've had, so I do have to keep it unplugged generally if I'm not using it. Read more

Did not live up to specs

JennaSysโ€”December 31, 2025

I got this power bank because of its advertised large capacity, however it did not seem to perform as well as I was hoping. Using the USB-C PD port, at 5V, it held a decent voltage up to about 2A, but at the rated 3A the voltage dropped down to 4.6V. However, at 9v it was solid up to the rated 2A. At 12V, the battery cut out hard at 2A and would not support the rated 2.5A at all. I was not able to get the PD port to output 15V. Load testing the power bank from 100% down to 0% at 5V and 2.5A, it lasted for 5 hours, putting out 12.5Ah and 60Wh. Doing the same test at 12V and 1.5A, it lasted for 3 hours and 15 minutes, and supplied 4.8Ah and again about 60Wh. So in the end, I was not able to get 30,000mAh nor 30W of output from this power bank. A full charge cycle from 0% back up to 100% takes about 5 and a half hours. Other than the advertised over-stated performance, this power bank actually isn't too bad for the price. I do like the fact that the charge level is always showing while in use, and it never gets warm when using it or when it is charging. I just wish the capacity of it was as good as the specifications say it is. Read more

Solid Build and Useful Features, but Performance Falls Slightly Short

Bubbaโ€”January 2, 2026

This unit makes a strong first impression with its metal casing, which feels sturdy fit, wellโ€‘constructed and portable. The builtโ€‘in flashlight was brighter than I expected and ended up being more useful than I anticipated. Charging took a little over four hours, and that was without fully draining it beforehand, so expect a fairly long recharge cycle. I didnโ€™t run detailed tests on every voltage setting, but based on general use, the performance felt a bit more optimistic on paper than in practice. With the premium look and solid build, I expected the output to match that same level of refinement. Overall, itโ€™s a decent device with good features and a quality feel, but thereโ€™s room for improvement in realโ€‘world performance. Read more
