Super Compact Power Bank that Charges Wirelessly

TORRAS – Slim MiniMag Wireless Power Bank
I like this thing! It’s super thin and magnetically attaches to the back of my I Phone 15 Pro. It fits perfectly just below the lens bulge and looks like it’s part of the phone. It’s thin (0.3 inch) and attaches tightly to the phone much like a Mag Safe Charger would.
The Torras was able to charge my I Phone 15 from 51% to 99% in a little over an hour using just 2 bars out of the 4 bars on the Torras display. Keep in mind if you want a faster recharge; use the included USBc cable for a direct connection to your phone. When the Torras Power Bank was totally spent, It took me about 2 hours to recharge it back to a full charge. There is some heat generated by the device while it is charging my phone as the power bank itself gets fairly warm. Supposedly there is a temperature monitoring device within the power bank to protect it.
My only complaint is you cannot attach the device to your phone without it charging. It’s great that it will immediately charge your phone as soon as you attach it, however some people may want to carry the power bank attached to their phone WITHOUT charging till you actually need it. I have been unable to make that happen. The “power” button on the device is a little funky. You can use it to read the current charge on the phone, and by holding the power button for 2 seconds the display goes into a continual up movement which I assume is the Low Power mode mentioned in the instructions, but I don’t know what low power mode is? I actually do not know what it’s really doing as the instructions are limited.
CONCLUSION: Overall I like the size and convenience of this device for charging my phone. It seems to be well made, with a clean, smooth, and attractive appearance. I do not care for the operation of the “power button”. Luckily I really don’t need to use that button for normal use. I do wish I could attach the device to my phone to have it handy, but without actually charging my phone. On a side note, you should be careful carrying this charger in your pocket or wallet while it’s near credit cards. The strength of that magnet could erase your credit card stripe. I would recommend the device to a friend as it works well for the intended use, and the price point is good. However, I would hope the manufacture updates it instructions, and/or addresses the power button operation.

Right out of the box, I was a little surprised by this power bank. I've had a stick type previously and this style not no where near the size. This unit is small...it's very thin compared to the others that I have used in the past. That's a huge benefit when it comes to taking it with me as I'm on the go. It fits in my front pocket with no issues or without creating a bulge. It's very light weight as well.
The item is easy to use. One press of the button turns it on. If you hold the power button for 2 seconds it places it in slow charge mode that will turn itself off after 2 hours...super beneficial when you are trying to reserve power and you fall asleep like I commonly do when I travel. I'm forgetful as well so that helps with this as well. Two quick presses turns the unit off. It has 5 lights that indicate the charge level which isn't necessarily easy to read if you don't know the item, but once you learn it then there are no issues.
It charges quickly using the provided USB-C to USB-C cord and it didn't feel like it was getting warm like other units. My iphone charges with no issues and will fully charge within an hour with the provided cord. My kids phone is older and don't have the USB-C port, but the Anker USB-C to lightening cable worked with no issues as well even though is said to only use the provided cord. The magnetic charging works well also, although I don't really use then together very much. The added power bank doesn't add a lot of wait, but it nearly doubles the thickness of the phone which honestly makes it easier to hold. The magnet is powerful, but not so that you can't easily transition from magnet to magnet free.
Overall, I love this power bank. I've only had it a few weeks but it's already made trips easier especially when my kids battery dies and we can't plug in somewhere.

Great little "range extender" type battery pack
|

This reviewer received promo considerations or sweepstakes entry for writing a review.
Normally my battery pack purchases are the larger 20k+mah variety. Ones that can charge multiple devices multiple times over. This is my first time using a battery pack that's on the smaller side, and I have to say I'm quite pleased with it.
The battery came to me with only 25% charge, so the first thing I did was charge it to full. It doesn't come with a brick though so you need to supply your own. I dug into my storage box and and old 12w Apple charger meant for earlier pre usb-c iPads. It charged the Torras from 25% to full in about an hour and a half.
I was going on a quick overnight trip and instead of bringing my usual setup of bricks and cables to charge my phone, and watch, I decided to just bring this and see how it goes.
I really enjoy that it can charge two devices at once. So I slapped it on my iPhone 14 Pro and plugged in a usb-c to apple watch cord a charged my series 7. I let it go over night on the night stand. In the morning both were fully charged and ready to go. I did notice that it will stop charging the devices once they reach 100% which is actually something that I enjoy. Rather than letting the battery continuously top off the device, it hits 100% then stops. To get it to start charging again without removing the battery pack from the device, just tap the power button and it'll turn on. Or you can remove it and put it back on then it starts up again.
After an over night charge of two devices, both around 50%, the battery pack still showed 50% itself when I plugged it in. So in theory you should be able to get a full charge of most phones and then a bit extra or a full charge of another smaller device like headphones or a watch.
I think of this as more of a "range extender" than a full on power bank. Since you can really only get 1.5 or so charges of a phone it's great for longer day trips where you don't know when you'll get to plug your phone in next. It's small enough to fit in most pockets. It's about as think as my 14 Pro, and similar width, but a bit narrower.
I only have two gripes about this, and they're really not that big and wouldn't dissuade me from recommending this. First is I wish the corners were more rounded. I run my iPhone 14 Pro caseless (*gasp*) and the corners of the battery should ideally follow the profile of the iPhone. These are pointier, and stick out ever so slightly beyond the iPhone. If you run a case, which most everyone does, then it would likely sit flush and not be a big deal.
2nd is the bottom 1/4 of the battery doesn't have the same grip that the magsafe ring does. By that I mean it's very easy to slide the bottom of the pack around as it's attached to your device. This could be a bare phone thing and not an issue with a case, but I can feel it slipping around as I'm holding and use the phone with the pack attached.
Neither of those issues prevent me from using it on overnight trips. This means I can free up my larger battery pack for other things, like running portable fans or string lights while camping.
Overall this is a great pack for overnight trips or long days that you can easily stick in a backpack or pocket. The light weight makes it easy to just take it with you, and slim size prevents it from taking up too much space.

Disclosure warning, this power bank is only compatible with iPhones that have mag safe cases. You can also charge your phone on the wireless charging pad, while charging another device using the included USB-C cable.
The MiniMag Power Bank has a sleek design making it easy to carry in your pocket or purse when either in use or not in use. The magnetic strength of the power bank is so strong that it stayed attached when I accidentally dropped my phone.
It's very simple and easy to use. Because of how thin it is, you can easily hold the phone comfortably in your hand, forgetting that it's even attached. It doesn't take very long for the power bank to fully charge. There's an indicator light on the back that shows the battery reserve, so you have an idea of when the power bank should be recharged. It does get slightly warm while in use but nothing that would cause concern or discomfort. It charged the phone from 20% to 100% in less than 15 mins. Overall, this is a super convenient portable charging option because I don't have to worry about wires pinching up in my pocket or bag. Would highly recommend!!!

This is not the expected performance of the TORRAS MiniMag power bank and is not typical behavior.
In rare cases, factors such as device power draw, background usage, or charging alignment can affect how quickly the phone gains battery percentage, especially on larger models like iPhone 13 Pro Max.
All TORRAS power banks sold through BestBuy are covered by standard warranty support, and if charging performance is abnormal shortly after use, our support process is designed to resolve it through replacement or service.

Thanks for sharing your feedback, Cakegirl. The MiniMag is designed primarily for iPhone devices with MagSafe. For Android phones like your S25+, a compatible MagSafe-style case is needed for proper alignment; otherwise the charger may not work as expected. TORRAS products purchased through BestBuy are covered by warranty support if a unit isn’t performing correctly. We appreciate you giving MiniMag a try, and your feedback helps us clarify product usage for all customers.

This has to be the best, portable, wireless, mag-safe power bank available! I wasn’t sure how this would work, but I have been testing this week and I can honestly say that it has been great to carry with me during my weekly commune and has performed as advertised.
The TORRAS Power Bank snaps on to the back of your iPhone fast and securely (depending on the case you have on your iPhone).
So with my testing, this power bank works best with iPhone without a case on it, or with a branded apple mag-safe case due to the magnet strength that these options provide. You can use an aftermarket case but the power bank does have a little weight to it and it might slide around a bit if the case does not have strong magnets.
So the instructions are a little confusing that come with the power bank so I will sum it up.
If you attach the power bank to the iPhone it will immediately turn on and start charging your phone. This is very convenient as it eliminates you having to press a button and turn it on yourself.
Once attached and charging it does seem to charge fairly quickly for the 7.5w output it has been advertised to have. There is a way to get the full 15w and that is to use a usb-c cable to attach the power bank to your phone.
Another cool feature this has, is when you have it charging your phone, you can connect another device using a usb-c cable and the power bank will actually charge both devices at once. I think this is a really cool feature that I didn’t even know it had.
The physical design of the power bank is very nice. They used premium materials and colors for the exterior of the device. I think it looks really good especially if you attach to the iPhone without a case.
This power bank does not only work with iPhones, it can charge anything that has a wireless charging capability. I have tested this with my AirPods case and another wireless phone that is non MagSafe and they both worked perfectly.
There is a slow charging mode that im not exactly sure why you would use, but i tested this and it does charge, but i cannot attest to the reason.
All in all this is a great wireless charger and its small and convenient form factor makes it a pleasure to carry around especially on a daily basis for commuting to work.
It gets a SOLID recommendation from me.

This reviewer received promo considerations or sweepstakes entry for writing a review.
The charger is sleek and very minimal. It can fit in any pants pocket. It only has one USB-C port to charge. It is a 5000mAH portable charger.
My phone charged decently fast for such a small form factor when I charged it. On the first initial charge for the portable charger, it didn't take too long to fully charge. Roughly less than 2 hours
The charger has flashing lights to indicate charging and is fully charged, It also comes with an integrated magnet on the back. You can keep it attached to your phone when charging. Keep in mind if you have a phone case, you will not be able to use this feature. Unless your case has metal inside it.
I do wish the charger had a standard USB-A port as well. That is the only drawback with the charger. you only get one USB-C port. Overall. it's a sleek, lightweight, and minimal charger that will charge your phone or smaller accessories. The charger won't take up much space and can be stored anywhere. It will keep a device charged all day when the time comes.

The Torras Slim MiniMag wireless power bank works extremely well with MagSafe iPhones as well as very well as a super slim power bank for devices that don't support MagSafe.
With the iPhone 13 Pro Max, it perfectly fits on the back side of the phone and doesn't extend much beyond the thickness of the camera bump. The magsafe hold is very strong and I can easily slide the combo into my pocket and keep charging. With my S22 Ultra, it is slim enough that I can carry it in my pocket with the provided usb cable and charge the phone at a healthy 15-18W. Wireless charging for the S22 ultra seems to be limited to about 5W but I don't have a good way to test this. That would be the expected charging speed for this type of device though. I also found the Torras power bank to be really useful for topping up my earbuds at the office - I can sit it on my desk and stick the charging case for my earbuds on it and not need to have wires strewn about everywhere.
#Final thoughts#
Who is this for: This is a perfect product for anyone with a MagSafe compatible device and is still exceptionally useful even if you don't have MagSafe on your phone. The high wired charging speed plus being able to use with wireless charging for a variety of devices is very handy especially for office workers.

I am in love with this battery bank so far. It is so thin and light that it can go into any shirt’s pocket, making it ultraportable. Even when paired with a phone, it can still fit in a pants’ pocket. The magnet is quite strong and can stay in place even when the case may be a bit thick. The bank can take some time to fully charge. There are small, discreet LED lights that tell the charge status and also when a device is charging. The included USB-C cable is on the short side, which is OK when charging a device right next to it but can be cumbersome when charging the bank. Luckily, I have plenty of long cables available. There is an on/off button to check battery status which is convenient.
Wirelessly, the bank charges my phone and earbuds quickly, and even faster when using the USB-C option. It even kept up with my handheld gaming device and tablet, extending my gaming or usage sessions. I also appreciate that I can charge 2 devices at the same time (wired-wirelessly), although charging time diminishes significantly. I did not notice the bank get hot at any moment, so it’s safe to charge while in the pocket. If there is a downside, is that the beautiful gray finish can be scratched easily.
In the end, I am quite pleased with this wireless bank, and the price is just right.
