Solid bulky power

Reviewed in the United States 🇺🇸 on January 20, 2023

I needed a larger power brick that was at least over 10,000 mAh, as my phone is 4380mAh alone. So, a single charge would drain a standard brick. So, I opted to give this a try. As far as real use so I was able to charge my phone with a 18%. I got a full charge out of it and then I moved on to a table that has 7040mAh. The tablet was drained to 0% and it managed to get it charged back to 29% and simultaneously charging a gamepad as I was still playing the game pad maxes out at 1050mAh. However, the Power brick was down to a single dot left. And if you know this power brick has a indicator of four green dots. So we have to extrapolate how much power is used based on four dots.
To calculate how much power I had left over. mAh is explained as follows:

The capacity of batteries is indicated as XXXX mAh (milliampere/hour).

The formula for calculation is as follows:

Capacity (milliampere/hour) = discharge (milliampere) x discharging time (hour)

E.g. Take a Ni-MH rechargeable battery with a capacity of 2000 milliampere/hour.

If you insert this battery into an appliance which consumes 100 milliampere current continuously, the operating time of the appliance will be around 20 hours mathematically. However, this is just a guideline since it varies depending on the performance of the appliance or the conditions it is used in.

Overall this battery pack is bulkier than most but has a decent power supply if fully charged for when you're out and about. If you have a back pack or a good way to stash this power supply away until you need it. The biggest plus of this battery is the fast charging capability, though I was only able to achieve good charge speeds using a type C to type C connection. The cable supplied is a standard USB A to Type C that didn't do the trick for me and my phone so I used it to charge a game pad. Always try to learn your devices mAh so you have a better understanding of how much you're actually draining.
I like it but, it's fat and bulky to store than most. The overall usability is there but if you don't have a good way to carry it you'll hate it.

A lot of power, yet quite antiquated, bulky, heavy and expensive. No QC 3.0 / 4.0 or PD available.

Reviewed in the United States 🇺🇸 on March 11, 2023

I own a bunch of these power banks some of which can serve as an emergency jump starter (much larger than this one).

This power bank does work, but at the current asking price, considering it does not have any fast charging capabilities, well... It makes it for a very hard sell, that is, if you care for that very important feature (QC 3.0 / 4.0 and PD).

For just about the same price you can find several different option here at Amazon that will have VOOC, QC 4.0, PD at 20,000mAh. Most importantly, quick charging of the power bank itself. This one? Nada.

So yeah, this particular charger would have been great for a lot of people... About 10 years ago. Nowadays, it's quite antiquated.

To make matters worse, the unit is pretty heavy and bulky.

Does it work? Yeah, but the asking price vs features completely renders this power bank obsolete against the heavy competition here at Amazon.

Overall, it's hard to recommend it, really.

BIG but lasts long

I received this TW brand portable charger and immediately noticed how huge it is! It's about as big as an iPhone max but about an inch thick. Additionally it's not very light, however, when you're desperate for battery power you'll take anything! Portability is probably the biggest issue I have with this charger, if you're gonna throw it in a suitcase or perhaps a larger purse then it's a non-issue, however if you think you're going to put it in your pocket, think again. I do like that it has three different charging ports so I can charge 3 things at once as long as one side is USB or or C. The value is definitely there, at this price I would say get one but if portability is your biggest concern then I would say look elsewhere. Other than that the battery itself lasts quite a bit, sometimes it seems to charge slower than other times not sure what that's about. It's made of high-quality plastic and seems like it will last a long time.

Its a good power bank, but its basic.

Reviewed in the United States 🇺🇸 on February 5, 2023

Vine Customer Review of Free Product( What's this? )

The first thing I noticed when I got this is how heavy it was. Usually that's a good sign when judging the quality of the lithium, but obviously not good for portability. The packaging is barebones, but it does come with a decent USB A to USB C cord. Now I think my cord is defective, it charges everything really slowly. The shell on the battery is a nice plastic and has a small window with green lights that indicate how much life is left. It has 2 USB A ports, a Micro USB, and a USB C port, so it has a good selection of ports to work with. I haven't precisely measured its capacity, but its definitely in the advertised ball park. Its very easy to use, there is a button on the side to "turn it on" and just plug in. Now in my testing I didn't even have to hit the button, I just plugged in and it worked.

My main criticisms of this product is that for its price and size, I would expect it to have extra useful features. For instance having wireless charging or a flashlight would go a long way. I mentioned above too, that something is wrong with the cord in the box.

Overall this is a good product, I just don't think its the best. I can recommend this power pack.

Lower wattage charging with less than stated capacity.

Reviewed in the United States 🇺🇸 on January 29, 2023

Vine Customer Review of Free Product( What's this? )

USB C output maxes out at 10 watts, not a big deal for passive phone charging, but that's gonna be a bit slow for bigger passive jobs or for active charging. The stated capacity of 74Wh is incorrect in my testing. I did one full charge/discharge cycle, then fully charged again before using this bank to recharge another device I have, that has a 208Wh capacity. I had that device on 65% which would have taken 72Wh to get to 100%. This device got it to 88% before running out of juice, which is just under 50Wh.

If the lower wattage and ~50Wh of capacity is good for you, this isn't a bad option for the money ($21.40 at time of review).

A lot of charge capacity, moderately compact, one fast charge port, but no special features

Reviewed in the United States 🇺🇸 on January 20, 2023

Vine Customer Review of Free Product( What's this? )

This power bank has a lot of capacity at 20,000 mAh. It also has two USB A and two USB C ports (one fast charging). The size is relatively compact relative to its capacity. Some of these power banks offer features like a led flashlight, wrist strap, carrying case, or digital display. The only feature on this device, beyond its core charging capability, is that it has led lights to indicate the remaining charge in the battery. I would recommend if you only want a basic power bank with a lot of capacity but don't need any extras.

A little too big

Reviewed in the United States 🇺🇸 on January 27, 2023

Vine Customer Review of Free Product( What's this? )

This power brick is massive. Way bigger than I thought with it being a 20k mAH. It will fast charge however and has 2 USB connections, a micro USB, and a type C connection. Tested on a galaxy s22 ultra. It works great. As far as portable the size makes it very awkward and it is a bit heavy as well.

Heavy but powerful battery

Reviewed in the United States 🇺🇸 on January 20, 2023

Vine Customer Review of Free Product( What's this? )

My biggest suprise with this battery was plugging my 16" MacBookPro into this battery and realizing it will charge it. You can charge via USB A or C and it will charge phone, iPad, computer, etc. It is a little heavier than I had expected, but it's about 5 1/2" x 2 1/2"x 1" and packing that much power, that makes sense. Put it in your backpack and take it along and you'll have power to spare.

Chunky boi charger

Reviewed in the United States 🇺🇸 on January 18, 2023

Vine Customer Review of Free Product( What's this? )

Love the capacity that this “portable” charger gives. But it’s not one you can really slip in your purse or backpack. More of a road trip / camping / power outage backup type of thing due to its weight. I know chargers can be heavy, but this one is a CHUNK, coming in at a full pound.

Otherwise love the amount of ports this has and the capacity. Clear indicator of battery life left is nice as well. Simple and sleek design.
