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.

A good quality power bank that will give you not quite a full charge (iPhone 12 at 80% battery health). It's very slim, lightweight and very neat when attached to the phone. Charges fairly quick. Perfect for an emergency charge and portable. Works well.

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.

WIRELESS Charge speed (winner = Anker)Anker technically wins because it is capable of Qi2 speed but this is very limited and tables off quickly as the devices heat up and the the most part only achieves Qi speed. Baseus and Lisen claim Qi equivalent speed (7.5W)WIRED Charge speed (winner = tie-break)All were found to deliver approximately 20W wired output equal to around 10% in 10mins on iPhone 15 Pro.FINISH (winner = Baseus)Baseus has the nicest smooth curved edges and is the only one to feature a soft silicone backing - especially nice if you are putting this on a ‘naked’ phone to prevent scratches. Baseus feels the nicest in the hand when attached to the back of the phone due to small size and curved edges.PORT (winner = Anker/Lisen)Personally I prefer the centrally aligned port which lines up with port on iPhone for streamlined wired charging. I wish Baseus had off entered the LEDs instead of the port.LEDs (winner = Baseus)Baseus and Lisen have 5 LEDs, four for charge level and one to show wireless charging which I think is redundant. Baseus has the nicest soft LEDs, I find Anker and Lisen to be a bit too bright, especially in dark environments. Although Baseus and Lisen have LEDs on the back so at least they you don’t see them if phone is screen up, unlike Anker which has LEDs on the bottom so they are always shining out.WEIGHT (winner = Baseus)Not a noticeable difference but Baseus takes it due to smallest size.Baseus 109g, Lisen 114g, Anker 122gSIZE (winner = Baseus)Baseus is the smallest of them all and the only one to fit within the footprint of my iPhone 15 Pro in a Wave case. Anker and Lisen go almost to the edges and same length as iPhone 15 Pro in Wave Case.CABLE (winner = Baseus)All come with USBC 60W cable, Baseus comes with nice braided cable, Anker and Lisen just come with a standard rubberised cable.PRICE & CONCLUSIONBaseus and Lisen around £20-30, Anker £40-50Baseus is the overall winner - smallest, lightest, nicest finish, best cable. In real-world use the Qi2 rating of Anker is rarely achieved and not worth the extra price tag. Yes there are 10K mag chargers that deliver consistent Qi2 speed due to better thermals but if you want the thinnest for convenience then all the 5k mag chargers are more or less the same in terms of speed. Best option is to use these mag chargers with a cable if you are concerned about max charging speed and heat.

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.

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.
