Such good potential with poor execution. The idea of having a small wireless battery pack that can stick to the back of any phone is amazing. However after using the iwalk for a few days I can say there are 3 major things keeping me from giving this product a 5 star review.1) This battery packs biggest flaw in my opinion is the size and output of the wireless charge coil inside. On 3 different phones I have tested this battery: Note 10, Lg G8 and iPhone XS. On all these devices I received a warning along the lines of weak charge detected or unable to detect power flow. A 10W and physically larger power coil would make this product much better!2. The sticky pad on the back of the battery is a joke. It is super thin and flimsy, easily punctured by nails and does not remain adhered to the battery pack. After using the battery for a few days and only removing it from my phones a hand full of times, the adhesive pad on the back is already almost destroyed.3. Last but not least the design of this battery begs for a kick stand. Not being able to stand up this battery with the phone while charging is a big missed opportunity. A small kick stand that extends to accommodate for a bigger phone would again make this a far better product!

If I paid $10 for this, I'd give it 4-5 stars, but this is NOT worth $25 for a few reasons: The guide booklet says that 3 of 3 lights lit means the portable device has somewhere between 31 & 100% power..If that's accurate, then the portable battery drops below 30% after less than 10min of independently charging my Note 5, so I'm constantly charging the portable device just in case. Pass-through charge is fine so long as the portable charger IS NOT fully charged - if it IS fully charged, then there's constant disconnect / reconnect of charge, and your phone vibrates nonstop while charging maybe 1% every 5min.Also, they include a little plastic card to cover the sticky part when it's not attached to your phone, and it ripped patches of the sticky surface clear off when I tried to remove it (and I didn't press it into the sticky at all)...so basically, if you want to get the absolute most out of this portable charger, make sure your current case accepts wireless charge, stick on the charger, and NEVER take it off...probably ought to look into a car mount that will hold your phone with this charger stuck to its back...and get used to your phone buzzing constantly when it does the disconnect / reconnect thing.

This battery works and is cheaper than using the all in one Apple Battery case. I prefer to keep my case thin and just attach to my Apple Leather case as needed. I would like to see it have a case itself to store in to keep the sticky pad clean when not using (that is why 4 stars.)Overall works well and I like it.

Small & Portable, Magnetic & Sticky the are the best features. However the pass through charging is flawed. After a while it would not charge my phone and the battery at the same time. I would have to charge the device and then charge my phone and place it back on the charger just to keep them both charged

Works great , charges my phone and light weight but the suction on the back was way too strong . I had to pry it off of my case and kind of ruined the sticky part on the back , idk if it’s meant to be permanent but that’s the only part I don’t like .

This power bank is so convenient! It had surprisingly great suction, charged my phone to about 60%, and is easy to use and fits in my pocket, albeit with a little added bulk. It does only work with smooth surfaces, so it works fine in the glass back of my phone and on my clear case, but otherwise I'm not sure how it would fare with a tpu style case. Overall, definitely worth it!

I have a galaxy s9 with an otterbox case on it and it did not charge my phone at all. I had it replaced to give it a 2nd chance. It was pretty easy to get a replacement and it came within 2 days. The 2nd one charged my phone but I had to take the case off and place the battery sideways. It was very inconvenient and pretty much made it useless to slip in my bag or pocket with the battery sideways. Not to mention my phone was more likely to break without a case. I gave it away to someone with a galaxy s10 because they had a thinner case and it charged their phone.

I can only charge my phone wireless so i purchased this. It gets both itself and my phone VERY hot, and actually will caution my phone to turn off for overheating. battery life is not good and takes a long time to charge something on it
