Anker Nano Power Bank, Ultra-Slim 5,000mAh Magnetic Battery Pack, Qi2 Certified 15W Max Ultra-Fast MagSafe-Compatible Portable Charger, Ergonomic Design, For iPhone 16/15/14/13/12 Only

I have spent days trying to decide on whether to buy this one or the MagGo Ultra Slim 10K. I ended up buying both so I could decide for myself and here is an honest comparison between the two. I tested them both with an iphone 16 max pro.Form factor and Weight: This one is a lot thinner and lighter than the MagGo Ultra Slim 10K. The MagGo is still small and lightweight but the nano is on a whole different level.Heat Level: Both gets equally warm, but definitely not hot. Your experience may differ if you use them under direct sunlight. I did my testing at around 25 degrees celsius, indoors.Build quality: I will have to give the edge to Nano here. It looks and feels a bit better.Magnet Power: This was my biggest concern as I saw some reviews saying the magnet power was weak or at least not as good as the MagGo Ultra Slim 10K. I use a pretty standard iphone case and I can confidently say that the magnet is equally strong. In fact, because this has a smaller form factor it holds better. I am guessing certain cases, even though labeled as magsafe, are interfering with the magnet and that is why people are having different experiences. I tested it without a case as well and both performed great even with all the shaking I gave, no difference at all.Charging Speed: The MagGo Ultra Slim 10K has a bit more than double the capacity and charges a bit faster. They both charge from 20 to 80 percent in about an hour with a 10-12 minutes difference. If you use them under direct sunlight and they get hot then the performance may drop due to thermal throttling but under normal conditions the performance difference is minimal.I have decided to keep the Nano 5K and return the MagGo Ultra Slim 10K because I don't need that extra capacity and the faster speed does not make that big of a difference in reality.

Works for iPhone 12 miniCan do about 1-2 chargesGets hot quite easily thoughBetter to let it cool downSticks well to MagSafe functionSo slim I can fit in my back pocket! Very convenient.

Great for a day out and easy to carry. Thin which makes it easy to carry. Charging is efficent and very sturdy. Magnet is very solid.

Haven't used it extensively yet, I mostly wanted to add a review to say that even though Android devices aren't officially supported, this works really well on the Pixel 9 with a MagSafe case. You don't get the full charging speed possible, but it's extremely convenient and useful. Despite Anker not making an official Android equivalent (get on it!) this definitely does the trick.

This newly released Anker portable power bank is game changing! Designed for recent iPhones, so it fits snugly on my iPhone 16Pro. They are not bulky at all in your pocket as it’s same thickness as my 16 Pro.This charger increases the battery life of your iPhone by roughly 1.5 to 2 times which depends on your model’s batt capacity. You can stop charging by press & hold the power button, so they will not charge your phone unintentionally even if you leave put them on and carry around. Heat and charging speed are acceptable.⚠️Please note that due to the energy loss of wireless charging, the actual charging capacity is approximately 3000 mAh. Alternatively, you can wire charge from its USB-C port, which allows more charging capacity.⚠️Please also note that this item is designed for MagSafe compatible iPhones, so not usable with iPhone 11 series or earlier & latest 16e.Otherwise, absolutely no drawbacks and this is the best portable power bank I've ever used. I think £50 is reasonable for the reliability of Anker. Defo recommend for iPhone users!

I thought I'd found an perfect portable charger for my phone with this item, but it fails its main purpose - which is highly unexpected for Anker.Positives:LightweightIncredibly small/thin with a sleek designFits pockets easily for travel/days outMagnet is strong and works wellNegatives:Heat doesnt dissipate properly which means it periodically stops or slows the charging speed down to prevent overheating. This results in it being unable to recharge my phone, instead only prolonging the battery available. This seems like a huge oversight for this product.I will use it for day trips into London where I may need a small power boost to get through the day, but cannot recommend this for general use.The reviews for the larger 10k charger are much more positive, so I may try this one as a travel charger instead.Dissapointing as Anker are usually a fantastic org and have never failed me in the past.

Good little battery. Fast charging, magsafe. Much lighter and more portable than my other one (10,000mAH), which is now my holiday battery.

Superb item. Fast charging, slim and lightweight.A definite upgrade on the slightly bulkier but also good Anker portable wireless charger.
