20000 mAh Wireless Power Bank with Anti-Slip Suction Cups, 18W USB-C Fast Charging Compatible with iPhone 16, 15, 14, 13, 12, 11, X, XS, XR, and Samsung Galaxy S25, S24, S23, S22, S21, S10, LG THinQ

I've tried so many external chargers it's ridiculous. Never had one I was in love with until this thing. I finally stopped trying new ones after discovering this suction cup guy.Know your battery size going in. My S24 is 4,000mAh. So the 20,000mAh pack is 5 extra batteries basically. The 10,000 one is 2.5 extra batteries.My favorite things about it:1) best wireless charging compared to every single other brand of charger I've purchased. The others just will not keep the wireless charging going longer 10 minutes and usually they all stop before then. This is for every phone I've had and my gf's who has a different brand. Also it is plenty fast at wireless charging.2) the suction cups make such a huge difference compared to brands that don't have it. PRO TIP: my naked S4 will not stick to it very well without the case on. I imagine this is true for most new phones. I mean who doesn't use a case nowadays anyway? But just fyi, the biggest 20,000mAh one they have can hang upside down from my cased phone with ease.3) highest quality construction.. It had a very dense, solid feel with a soft, almost rubbery finish that makes it comfortable to hold. It's also on the smaller side for 20,000mAh batteries.4) really does make a great gift. I don't know anybody who doesn't love these things that I've bought one for or just told them about.Buy the 20,000mAh thick one and a 10,000mAh thin one. They're the same area but different thickness. So they fit perfectly behind the phone. The smaller area 10,000 one really isn't for phones in my opinion unless it's a very small phone. I keep it in the car as backup.I've purchased at least 20 external chargers over the years and this is my favorite.Phone is Samsung Galaxy S22 and now S24.

I had a battery pack for my phone previously. But it required a wire to charge my phone. I bought this because I like the fact that I could charge my phone wirelessly and I liked the fact that it had the section to the phone. Quite honestly this is amazing it's lightweight the section is strong and I can almost use the battery pack as a handle when going through my phone. The battery life of the battery pack seems pretty good I will say it takes a while to charge this batterypack. Overall and thrilled with my purchase and wish I had bought it sooner.

I bought this because my old weaker one broke, not the wireless feature, but the wired feature, so I couldn’t use it as a normal power bank, so I got an upgraded one, and it’s amazing! It charges really fast, and sticks really hard. Although, the “simultaneous charging” is not really true, as I tried it, but only the one connected wired to the bank was the only one charging. Still really good for single use.

The media could not be loaded. These chargers are amazing! No more worrying about missed calls or messages due to a low phone battery. The TechSmarter charger is convenient and powerful.This company's service is something way beyond what other company's are doing. I inadvertently bought the wrong charger for my Galaxy S21 Ultra. Instead of reaching out to support right away, I made due with what I'd ordered. After 2 months of being slightly frustrated, I reached out to TechSmarter -- way after the return period. No worries, their support recognized I ordered the wrong product for my phone and sent me a replacement; no questions asked. They even followed up to ensure I was happy with the correct charger.If you are ever in the market for a travel charger, this is the company to offer from! 😀

The pros: This does fast charge my Samsung Galaxy S10 and the battery holds enough juice to recharge it more than one time.The cons: The suction cups will not stick to the Otter Box case that encases my phone. I primarily bought this thinking I could stick my phone to the suction cups and let it charge, instead I have to lay the charger flat then move my phone around until I find the sweet spot and it starts charging.The only reason I'm not giving this a 1 star review is because it does charge my phone fast once I get it positioned so that it will charge.

This works perfectly as intended. Charges your phone quickly, suction cups work great, takes an overnight charge to be full but after that you can take it anywhere. Worth every cent.

Don’t waste your money on this product. I purchased it just over a year ago and only used it a handful of times. Never damaged it or dropped it. It worked fine when I first received. After a couple of uses, this charger will not charge to its full capacity. It’s stops at one light indicator. I double checked to make sure it just wasn’t the indicator light problem, nope it wasn’t. It was the portable charger itself. Piece of crap. Go with a reputable company to get a better quality product.

With Samsung S21 Ultra... With case and without case. Very Very slow charge (does not fast charge wirelessly) .. has to sit perfectly (often turns off) turns off at 100% and lets the battery run down from there. (you have to play with it when it goes down and basically reseat it / turn on / off again.Not really reliable enough when in the car.
