Customer Review
Reviewed in the United States 🇺🇸 on June 27, 2021
Over that 10 month period it should equate to roughly 150 full charge cycles and I still don't notice any real drop in capacity. There obviously is but it's hard to tell. 8-10 hours powering led strips outside every night has always consumed roughly the same amount. It is been in damp environments, below freezing weather, high heat and survived some decent drops on pavement.
This thing is incredibly reliable. I have owned a lot of these power banks for the same uses and this one has outperformed them all. I would love to see this exact power bank except with an updated screen, a proper manual and a change in how modes are changed. Since this has become my best power bank I don't use it for projects that would need low power mode but I still run in to that reset issue by accidently holding the button in. A readable screen and that fixed so it doesn't trick you to thinking it's charged would make this perfect.
I'm sorry this review became so long with these updates. I just hope it helps people in making an educated purchase. This is one of the good ones. It's a shame some uneducated reviews are made about the capacity that make false claims because they don't understand what they are looking at. This is a good buy and exactly as advertised. At this point I feel comfortable saying people will get their moneys worth and then some with this.)
(This is the follow up after a few months of daily heavy use. That "burnt electronics smell" I noticed went away after the first month and didn't seem to cause issue. For at least 3 months I have used and charged more than 60% of it's capacity daily. Despite that I still don't notice any abnormal loss of capacity. If anything it seems to be holding it's capacity longer then every other power bank I have owned with the exception of one that cost 50% more and has had much less use.
After having more time with it I learned that I was mistaken about a few features. A proper manual would save people a lot of aggravation. Before I said it will show the output for each port but that is not the case. The USB C port seems to be tied to the lightning port and the display will show both as one by combining the amperage draw of each port. All 4 USB A ports are also tied together so it will only cycle between the total of those 4 ports and the total of the other 2 ports. The problem with them being tied together is it can not use different output voltages for ports that are tied together.
If you are using the red quick charge port at 9v and you plug something else in the black 5v ports then you will no longer get 9v out of the red port. It will drop down to 5v like others. The same happens if using the lightning port and the USB C port at the same time. In order to use different voltages you have to use one USB A port and the USB C/lightning port. They don't interfere with each other.
Another mistake I made was about the flashing L and holding the button in. It is definitely the Low current mode but holding the button down also seems to reset the power banks memory. I noticed sometimes after coming out of low power mode it will reset that charge status to 100% even if it is really only 20% charged.
With this power bank it is an absolute necessity to confirm the charge status. While charging look at the voltage and amperage being used. When it's actually at 100% it will drop to below 5v and 0.2amps and eventually stop. Once you hit 5v 0.2amps you can be assured you are at least 99% full. It can show 100% yet still have a good hour of charging going at 40watts or more. You must push that button and check what is going on before believing that 100%
It's too easy for the display to reset and show 100% when it isn't so always double check before you need it. In the beginning you should never trust seeing 100%. I would actually recommend just holding that button down and resetting the moment you take it out of the box and then charge it until it shows it isn't drawing a current anymore. After that point you should be fine as long as you don't need the low current mode or think you accidentally had the button held in.
I was slightly underwhelmed in the initial review but it has now exceeded my expectations. It has spent nights outside below freezing and hasn't had a single day off in months but still holds seemingly the same capacity and works perfectly outside of never reaching the full claimed charging speeds. The reliability makes up for that short coming. I am extremely impressed and recommend this to anyone that needs a lot of portable capacity. I have never had a power bank used this much and in such harsh conditions hold up so well.)
For now this review does not take into account its reliability. I have not had it long enough to make any informed claims about that. I have given it a couple charges and tested charging with a little less than two dozens devices. To be completely honest I expected more considering the price of this. Given the behavior of the power bank with all of those devices leaves me thinking I paid nearly twice the price of a similar size power bank just for faster charging of the power bank. Even when charging I cant reach the max charging speed supported by whatever adapter I try to use.
I have a compatible 65w charger that is capable of outputting 20v at 3amps and it reaches the full output wattage on all of my other devices that support it. Even though this power bank claims to support that output it maxes at 19.5v at 2.1amp. I don't expect it to show 20v and 3amp but there is no reason I shouldn't be seeing 19-20v above 2.5amps. I did not drain the power bank all the way down so maybe it is possible it only reaches above 60w charging when empty. Even though that's possible I doubt it. I did get it down to 26% and it still maxed at that 2.1amps peaking around 40watts.
My concern is that short coming may be from a temperature issue. There is a spot towards the outputs that gets rather warm and even gives off a hint of that burnt electronics smell if you get close to it. It's very faint but the power bank isn't even charging at the full 60watts. For some reason it refuses to so I don't know if it gets worse and how bad it can get. It still charges rather quick but even at 40watts you are somewhere around 5 hours for a full charge. Even when the display says 100% there is a good 40 minutes of charging left. It drops down to 5v then and starts charging at 2.5amps. Even at 5v I haven't seen it approach 3amps.
Charging other devices doesn't seem to meet spec either. There always seems to be 25% headroom left no matter what it is doing. Maybe I am extremely unlucky and everything I own isn't suited for it. While I have issues with the wattage claims I do think the 30,000mah is relatively accurate. I was able to charge a Oneplus 9 four times and a Galaxy S9 almost twice which is roughly 23,000mah making it as good or better then the two other 30,000mah banks I have. There is always going to be a loss considering conversion and it seems to be as it should. I even seem to be getting better than the 18,000mah rated capacity they listed on the bank. That number does not mean it is not a 30,000mah power bank. Chances are the batteries inside are 3.7v with either three polymers or a bunch of li-ions. Boosting the voltage decreases the mah and you also have loss with heat. The conversion loss happens with all of them. Most just don't list the expected capacity after loss.
The screen is kind of garbage like most everyone says. It's good in darks places and ok inside but outside its unusable. It's a shame because it is nice being able to see the output voltage and amperage. It is also what made me look into the way this power bank charges multiple devices at once and first realize how terrible the documentation for this device is. There is almost nothing anywhere that tells you how to properly use this power bank and it can lead you to think some things aren't working as it should. This is already too long but I will try to explain some of it.
The manual is poorly written and what is there tells you nothing about its features or how to use them. Nowhere does it say the display cycles through outputs and will list the power bank battery percentage then voltage and amperage of the output. If two or more devices are plugged in it will then cycle to the next port on the fourth button press starting again with the power bank battery percentage followed by voltage and amperage. The bad part is there is no indication of what port it is showing. You either have to know your devices or double check on the device itself.
It also seems to have an always on feature if you hold the button down until you see the screen reset. It will now flash a L after showing the battery percentage and the power bank will output constantly regardless of how low the amperage is. Normally if the amperage gets below 200mA it and most power banks will timeout stopping the output. After holding the button down to get the L this power bank will keep powering whatever it is you have connected regardless of how low the current draw is. It is a handy feature and one I really like for emergency purposes. Just like previously there is no mention of this feature anywhere.
At the end of the day I expect better for the price. There is no excuse for the manual being how it is and the lack of information available on their website. The below spec speeds and slight smell when warm doesn't help its case either. It seems like they put no care in this product at all. It seems to have decent quality cells, ok features and a large selection of inputs and outputs. They just didn't bother documenting any of it to make it feel more premium than those cheap power banks that lie about their capacity. Despite its shortcomings it at least seems to have an accurate capacity rating. Good batteries aren't cheap so maybe that is enough but for the price they should do better.
If I notice the smell or anything else gets worse I will edit this review to reflect that. If for some reason I learn the reason for the rated wattage not being reached is my fault I will also update. Until then this is just a mediocre power bank. You can definitely do worse but its possible to do better.
(Here is yet another update. It's on sale at a decent price currently so it seemed like a perfect time to update. It has had 10+ months of daily use and it still works just as good as new. Almost every single night I use at least 50% of it's charge. During the day I use it in the car to charge stuff and it gets charged every day.
Over that 10 month period it should equate to roughly 150 full charge cycles and I still don't notice any real drop in capacity.

All 4 USB A ports are also tied together so it will only cycle between the total of those 4 ports and the total of the other 2 ports. The problem with them being tied together is it can not use different output voltages for ports that are tied together.
If you are using the red quick charge port at 9v and you plug something else in the black 5v ports then you will no longer get 9v out of the red port. It will drop down to 5v like others. The same happens if using the lightning port and the USB C port at the same time. In order to use different voltages you have to use one USB A port and the USB C/lightning port. They don't interfere with each other.
Another mistake I made was about the flashing L and holding the button in. It is definitely the Low current mode but holding the button down also seems to reset the power banks memory. I noticed sometimes after coming out of low power mode it will reset that charge status to 100% even if it is really only 20% charged.
With this power bank it is an absolute necessity to confirm the charge status. While charging look at the voltage and amperage being used. When it's actually at 100% it will drop to below 5v and 0.2amps and eventually stop. Once you hit 5v 0.2amps you can be assured you are at least 99% full. It can show 100% yet still have a good hour of charging going at 40watts or more. You must push that button and check what is going on before believing that 100%
It's too easy for the display to reset and show 100% when it isn't so always double check before you need it. In the beginning you should never trust seeing 100%. I would actually recommend just holding that button down and resetting the moment you take it out of the box and then charge it until it shows it isn't drawing a current anymore. After that point you should be fine as long as you don't need the low current mode or think you accidentally had the button held in.
I was slightly underwhelmed in the initial review but it has now exceeded my expectations. It has spent nights outside below freezing and hasn't had a single day off in months but still holds seemingly the same capacity and works perfectly outside of never reaching the full claimed charging speeds. The reliability makes up for that short coming. I am extremely impressed and recommend this to anyone that needs a lot of portable capacity. I have never had a power bank used this much and in such harsh conditions hold up so well.)
For now this review does not take into account its reliability. I have not had it long enough to make any informed claims about that. I have given it a couple charges and tested charging with a little less than two dozens devices. To be completely honest I expected more considering the price of this. Given the behavior of the power bank with all of those devices leaves me thinking I paid nearly twice the price of a similar size power bank just for faster charging of the power bank. Even when charging I cant reach the max charging speed supported by whatever adapter I try to use.
I have a compatible 65w charger that is capable of outputting 20v at 3amps and it reaches the full output wattage on all of my other devices that support it. Even though this power bank claims to support that output it maxes at 19.5v at 2.1amp. I don't expect it to show 20v and 3amp but there is no reason I shouldn't be seeing 19-20v above 2.5amps. I did not drain the power bank all the way down so maybe it is possible it only reaches above 60w charging when empty. Even though that's possible I doubt it. I did get it down to 26% and it still maxed at that 2.1amps peaking around 40watts.
My concern is that short coming may be from a temperature issue. There is a spot towards the outputs that gets rather warm and even gives off a hint of that burnt electronics smell if you get close to it. It's very faint but the power bank isn't even charging at the full 60watts. For some reason it refuses to so I don't know if it gets worse and how bad it can get. It still charges rather quick but even at 40watts you are somewhere around 5 hours for a full charge. Even when the display says 100% there is a good 40 minutes of charging left. It drops down to 5v then and starts charging at 2.5amps. Even at 5v I haven't seen it approach 3amps.
Charging other devices doesn't seem to meet spec either. There always seems to be 25% headroom left no matter what it is doing. Maybe I am extremely unlucky and everything I own isn't suited for it. While I have issues with the wattage claims I do think the 30,000mah is relatively accurate. I was able to charge a Oneplus 9 four times and a Galaxy S9 almost twice which is roughly 23,000mah making it as good or better then the two other 30,000mah banks I have. There is always going to be a loss considering conversion and it seems to be as it should. I even seem to be getting better than the 18,000mah rated capacity they listed on the bank. That number does not mean it is not a 30,000mah power bank. Chances are the batteries inside are 3.7v with either three polymers or a bunch of li-ions. Boosting the voltage decreases the mah and you also have loss with heat. The conversion loss happens with all of them. Most just don't list the expected capacity after loss.
The screen is kind of garbage like most everyone says. It's good in darks places and ok inside but outside its unusable. It's a shame because it is nice being able to see the output voltage and amperage. It is also what made me look into the way this power bank charges multiple devices at once and first realize how terrible the documentation for this device is. There is almost nothing anywhere that tells you how to properly use this power bank and it can lead you to think some things aren't working as it should. This is already too long but I will try to explain some of it.
The manual is poorly written and what is there tells you nothing about its features or how to use them. Nowhere does it say the display cycles through outputs and will list the power bank battery percentage then voltage and amperage of the output. If two or more devices are plugged in it will then cycle to the next port on the fourth button press starting again with the power bank battery percentage followed by voltage and amperage. The bad part is there is no indication of what port it is showing. You either have to know your devices or double check on the device itself.
It also seems to have an always on feature if you hold the button down until you see the screen reset. It will now flash a L after showing the battery percentage and the power bank will output constantly regardless of how low the amperage is. Normally if the amperage gets below 200mA it and most power banks will timeout stopping the output. After holding the button down to get the L this power bank will keep powering whatever it is you have connected regardless of how low the current draw is. It is a handy feature and one I really like for emergency purposes. Just like previously there is no mention of this feature anywhere.
At the end of the day I expect better for the price. There is no excuse for the manual being how it is and the lack of information available on their website. The below spec speeds and slight smell when warm doesn't help its case either. It seems like they put no care in this product at all. It seems to have decent quality cells, ok features and a large selection of inputs and outputs. They just didn't bother documenting any of it to make it feel more premium than those cheap power banks that lie about their capacity. Despite its shortcomings it at least seems to have an accurate capacity rating. Good batteries aren't cheap so maybe that is enough but for the price they should do better.
If I notice the smell or anything else gets worse I will edit this review to reflect that. If for some reason I learn the reason for the rated wattage not being reached is my fault I will also update. Until then this is just a mediocre power bank. You can definitely do worse but its possible to do better.
