Purchasing Notebook/Laptop Battery
Notebook/Laptop Battery by iTEKcanada.com are usually lower in price and usually exceed the performance of OEM Notebook/Laptop Battery. Many of iTEKcanada.com’s Notebook/Laptop Battery use the same battery cells as OEM batteries.

What is mAh / Wh?
These ratings show battery`s capacity. Think of them as gas in your car tank, the bigger the tank, the more fuel it will carry and your car will drive longer. Same with these batteries, the higher the mAh/Wh, the longer your device will run between recharges.

Will your higher capacity (mAh/Wh) Notebook/Laptop Battery work in my device, even though my original battery has a smaller rating?
Definitely! Our batteries are designed to be 100% replacements for original batteries. Higher mAh/Wh rating means longer run time between recharges. The higher the rating the slower it will take for the batteries to drain down. Meaning you will get longer talk time with a higher mAh rating. In other word, higher is the mAh number, better it’ll be for your device.

Quality and Safety
This battery contains advanced technical components and has been tested according to strict CE safety standards. The battery contains a chip that prevents overcharging and short circuiting. Next to this the battery is made from high quality cells that do not suffer from a so-called 'memory effect'.'

Factory Fresh
Batteries lose performance over their lifetime, even when they are not used. Many importers and resellers store their batteries in stock for a long time before they are sold. iTEKcanada.com sends products almost directly from the factory, so you are sure that you will get a brand new high quality battery!

Thin, secure, with plenty of juice
Color: White, Color: White
When I purchased the iPhone Air, I bought into the hype that the battery life might not be sufficient for all day. Putting aside that in reality, my iPhone Air lasts just fine most days, I wanted a MagSafe power bank I could take with me when I was away from home. After reading about the Apple produced battery for $100, I opted for the Anker for about half the price. Pros: Very thin; strong magnets that attach to any MagSafe case: fits inside the edges of the Apple bumper case; packs more juice than the Apple version; works with any iPhone so I can share with my family. Cons: It is still heavy; you can't recharge the battery via MagSafe, only USB-C; color options didn't quite match the iPhone Air colors. I purchased the Sky Blue iPhone Air and the Anker 'Green' seemed off, so I opted for the white.

Good, but a little spendy and lower capacity for value
Color: Black
I have used this plenty at work anytime I forget to charge my Samsung S25 Ultra (which has a 5,000mah battery) or am using it intensely, often for work. The charge time is actually the new Qi 2, so it's not bad. It's not a fast charger, but it's super good enough to not bring a cable. It's slim enough to not care as well. I am a nerd and keep it in my cargo pocket which also helped save the day for some poor lady who needed to charge her iPhone, so I lent that to her for a short bit. It's super unubtrusive to keep on you so it's handy if or when you need it, or need to help. I like Anker as a brand, and lean to them for battery banks. I have several of their batteries, so I figured I will eat the premium to get the portability. I like the form a lot, and the magnetc retention is rock solid. Charge speed is fair, and heat isn't what I would call concerning if this isn't something you do with frquency. A 5,000mah battery will not go far in real world use. One full recharge, which is perfectly suitable. The price is what will hurt. You can get a conventional bank for the same with much more capacity. It won't be as slim and likely won't be wireless (or as fast). I rather like this battery but am hesitant to recommend it. It really is a case of do you want slim and portable or capacity and budget? It is a solid product, however you decide.

Best travel MagSafe Charger
Color: Black
I recently purchased the Anker Nano MagSafe Portable Charger, Ultra-Slim 5,000mAh, and it has quickly become one of my favorite everyday tech accessories. The compact design and reliable charging performance make it incredibly convenient for keeping my iPhone powered throughout the day, whether I’m commuting, traveling, or simply away from an outlet for extended periods. One of the first things I noticed was how slim and lightweight the charger feels. It attaches securely to the back of the phone with MagSafe, making it easy to use while still comfortably fitting in a pocket or small bag. Unlike bulkier power banks, this one maintains a sleek profile that doesn’t add unnecessary weight or thickness. Charging performance has been very reliable overall. The 5,000mAh capacity provides a helpful boost when my battery starts running low, and the magnetic connection stays firmly in place during use. I also appreciate that the charger delivers consistent power without overheating, even during longer charging sessions. The build quality is excellent, which is something I’ve come to expect from Anker products. The materials feel durable and premium, and the minimalist design looks clean and modern. It arrived well-packaged and immediately gave the impression of being a high-quality accessory. Another feature I appreciate is how simple and convenient it is to use. There’s no complicated setup involved—just snap it onto the back of the phone and charging begins automatically. It’s especially useful when traveling or during busy days when carrying cables around can be inconvenient. After using it regularly, I’ve been very satisfied with its reliability and portability. It keeps my phone charged when I need extra power most, and the ultra-slim design makes it easy to carry everywhere without noticing the extra bulk. Overall, the Anker Nano MagSafe Portable Charger, Ultra-Slim 5,000mAh is a dependable and thoughtfully designed portable charger. It offers reliable charging performance, excellent portability, and premium build quality. I would definitely recommend it to anyone looking for a compact and convenient MagSafe-compatible power bank for everyday use.

A really great portable charger
Color: Golden
Works great with my Samsung Galaxy S25 in a magnetic case. I love the small form factor, which means I can keep it on my phone to charge while I'm using the phone when I need to. It also means it's incredibly easy to take any time I leave the house, not just when I travel. It does get pretty warm, but I find that keeping the phone face down helps that a lot. And of course using the phone while it's charging makes it hotter. One note if You're like me and you've never used one of these: there's a small button on the side that activates or deactivates the magnet. I thought the magnet had died because it was no longer attaching to my phone. Then I randomly held the button down and it snapped right back on. It's a useful feature now that I know that it's there, so I don't leave the magnet on when it might be near swipeable cards in my bag. Funny they don't mention anything about that in all the product images, but now I know.

Heat and Charging Complaints Are Unjustified
Color: White
Good product overall. I was going to give it 4 stars because it hangs slightly off the bottom of my iPhone 15 Pro but I realized it says 16/17. Those models might have the MagSafe ring slightly higher on the phone in which case it would fit cleaner. I was worried about Heat after reading the reviews. All inductive charging systems generate waste heat and all charging generates waste heat. It’s nothing extreme here. If it’s in your pocket without air flow around it, it gets quite warm on the phone for sure. In my hand, using the phone for a while plane flight, there’s enough flow that it’s just a bit warm. Battery life is as advertised. It’s somewhere around a charge or so, I didn’t check this scientifically. Plenty to keep you topped up through a cross country air trip. It’s very small and much nicer to have on the phone than some other models I’ve borrowed. Reviews have some complaints that it “doesn’t charge the phone”. That’s a goofy complaint. If the phone is dormant it will add charge percentage. If you’re streaming and emailing, on Bluetooth, and WiFi all at once you’re going to use power about as fast as it can supply without it spiking temperature. I was very happy to just sit at 75% my whole flight while constantly using my phone. It doesn’t matter if it added percentage, you don’t get this to charge your phone, you get this to extend the battery and it does just that. If you can leave your phone out of your pocket where it can breath/cool a bit you’ll be happy with this. Good product and some seem to be expecting it to cheat physics.
