Experience with iPhone 16 Pro in original transparent MagSafe case and magnetic charging - recharging from zero to 33% and then it dies. From 50% to 70% and it dies (phone in pocket without use). In summer temperatures, it overheats to the point that the iPhone reports "iPhone needs to cool down" even in casual use. Moreover, it loses charging efficiency (conversion to heat) even more. I probably wouldn't recommend it to anyone who wants to travel somewhere and actively use the phone or take pictures. I have a similar Qi2 with 5000 mAh and it's about something else, the size and weight are slightly bigger, but it can already recharge the percentages relatively quickly and then I can unplug it and use the phone for a while without the charger. I would only take this as an ultra portable last hope or charge it with the mini cable that comes in the package.

The power bank appealed to me mainly because of its practicality - how thin and light it is. The magnet sticks to the phone very well and I have never once noticed that it has fallen off in any way. The only thing that bothers me is overheating, which is not entirely pleasant, I also noticed that the capacity of the powerbank is not 100% and the phone only charges from some small part, but on the other hand, it would probably have to be bigger and stronger and that would bother me much more. As a minor rescue on the go, it will suffice 😊
Very practical for travelling thanks to its size

The main reasons why I bought this powerbank was the minimalist design and aluminum body, it powerbank fulfilled perfectly. I am adding here some basic information I have measured in use. Dimensions 102x70x6 mm, which are beautiful dimensions. The charging time of the power bank when fully discharged was approximately 100-120 minutes. I already take charging via USB C for granted. Charging the phone ( Iphone 16 Pro ) took roughly 90-120minutes until the powerbank was completely drained and the phone got 25-35%. Unfortunately, I have to write the reasons why I cannot recommend the powerbank to others. The first reason is that it is not possible to detect the capacity of the powerbank as it has only one diode and it only lights green and red. And the second and main reason for my non-recommendation is overheating. After about half an hour, the temperature of the powerbank rose to 56 degrees, causing the phone to overheat and disconnect charging.

Hello, thank you for your review. The EM31 Powerbank is one of the world's thinnest wireless power supplies, and maximum mobility is paramount. The smallest possible dimensions obviously mean a certain compromise in capacity, but it normally charges the phone to 40-50% and that's certainly enough for half a day extra. Heating is typical for all powerbanks, cooling here is effectively assisted by the aluminum body. Multiple LED or display indication has given way to the maximum possible capacity of the cell inside. From a power bank of this size you cannot expect the same parameters as other models, it is a product that has its own specifics and fulfils its purpose without fail. Thank you and have a nice day, Ondřej - Alza expert

The Epico UltraPack EM31 3000 Slim Mag+ impresses at first glance with its elegant design and quality workmanship. The aluminium body feels premium, is durable and fits perfectly in the hand. Its compact size makes this power bank the ideal travel companion. MagSafe support also ensures easy attachment to the phone, which is especially appreciated by iPhone users. Pros: - Design and workmanship: The elegant aluminium surface not only looks good, but is also pleasant to the touch and resistant to damage. - Compact dimensions: The slim design makes it easy to carry, whether in your pocket or handbag. - MagSafe compatibility: Practical attachment to the phone without the need for cables. Cons:
Although the power bank impresses with its appearance, it lags behind in practical use. The first problem is capacity. The manufacturer claims 3000 mAh, but in real use, the power bank can only charge the iPhone 14 Pro (with a capacity of 3200 mAh) to about 50%. This corresponds to a power transfer of roughly 1600 mAh, which is significantly less than one would expect. Another negative is the lack of a charge status indicator. The power bank has no way to display how much charge it's at, which is impractical and often frustrating, especially when you don't know if you have enough power to charge it again. Overheating of the phone during use is also very annoying. When charging for longer periods of time, the phone gets noticeably hotter, which not only degrades comfort, but can also lead to faster wear and tear on the phone's battery. Conclusion:
The Epico UltraPack EM31 3000 Slim Mag+ is a beautifully crafted powerbank that disappoints in practice. The low real capacity, the lack of charge indication and the problem with overheating of the phone make this product more of a stylish accessory than a reliable power source. For users looking for a truly functional solution, you're better off looking elsewhere. Rating: ⭐⭐/5

The power bank is great. It is incredibly thin and light, which is not common with other models. Perfect for travel or work - it fits easily in your pocket or handbag and doesn't get in the way: ). The magnet holds reliably even when I use the phone while running, just need a quality cover. The capacity could be larger, but then it wouldn't be as thin. That's great for me: )
Thin and light, great for travel and work

A sleek MagSafe charger that not only with its design, but also with the power of the magnet is what I needed on the road. I now have this one, but have already ordered another piece with a higher capacity for a greater sense of security. If you're a person who uses your phone to the fullest in any way, this is exactly the device you want to have on hand at all times.
