Portable Charger 30000mAh imuto Power Bank X6 USB External Battery Pack Android Cell Phone 3-Port 3.4A Output Fast Charging Compatible with iPhone 13 Pro Max, 12, Samsung S21, iPad, Nintendo Switch

The first thing I thought when I got the box open was simply WOW. This thing feels like a brick. Its solid and built like a tank.I found that while it’s a complex device internally it’s very simplistic externally. You don’t have to be in any way technical to use this device. If you know how to plug your phone into a charger you can handle this, it’s that simple.~Intelligent charger, no settings, just plug in your device and let it sense what the device needs~Operation is simple, plug in a cable and then plug the cable into your device, phone or tablet~The side mounted button can be depressed to have the display show remaining capacity~When it starts charging any device the display lights up, even something that takes very little current like a BT headset, then after a minute the display goes out to save powerThis is the heaviest power bank I have ever encountered and rightly so, it has the greatest capacity by far of any power bank I have or have looked at. If you work the numbers, 30,000mAh is 30 amps. Now the arithmetic I'm going to use here is not exact but I use it as merely an example of just how much capacity this thing has, a standard compact car battery is usually rated at a reserve capacity of about 75-90aH. what we have here is a small device that has a capacity that equals about a third of a compact cars battery. Again, please don't jump on me for the arithmetic, I'm just making a point to give an idea of how much capacity that can be put into a small space when Li-ion batteries are used. Plus this power back provides varying voltages that some devices need. You may have seen the very small "boosting" devices that can be used when your car battery is dead, you can get your car started with them. This is the same size physically as the one I have and has more capacity than most of those devices.How fast it can charge a phone all depends on your phone, the shape your battery is in - is it new or getting old, temperature, and other variables not to mention make/model of the device being charged. I could give you all manner of figures, capacity reached over time but this means nothing when the devices you have aren’t the same or the batteries are in better or worse condition than what I was charging.-||- The important thing here, this is a smart charger that will get your device charged as quickly as your device will allow it.~Like any good power bank there's a readout letting you know how much of its full capacity is left. This read out in percentage, see image below where it shows 66%For performance, this is a Qualcomm 3.1 certified charging device. No matter what your current devices needs are for voltage or current to achieve a fast charge this power bank can provide it. If you have a device that can fast charge at 5v, 9v plus or 12v (or somewhere in between) but only have the one charger that came with the device, this becomes your second charger. And the best part is you can charge this from any USB power source. You can have three devices charging at the same time and each one will get the right voltage and current that it needs.~Like any quality power bank it has multiple USB A ports but it also has an additional USB C port that newer devices now use~The USB C connector works as both a charging port for the power bank or for charging a phone~The micro USB port is strictly for charging the power bank batteries~The internal circuitry makes sure your devices get the right voltage and current, no over chargingTo charge the power bank you can use any USB charger or even a PC or laptop but a dedicated charger would be a better way to go. You can use the charger that came with your phone or tablet. A completely flat battery will take some time to charge, don’t expect to get a full charge in a couple of hours even with chargers that put out 2+ amps. This is the kind of thing you let charge overnight to ensure its fully charged before heading out the door.It took me a couple of days charging multiple devices before I drained the battery. At times both USB A ports were putting out their max current and the power bank remained cool. This is an important item. Electronic components don’t like heat, it causes them to break down. The cooler something is when its charging or discharging the longer it will last.**The USB connectors are a very snug fit. This is an important item that not many people think or know about. Lose connectors can actually cause damage to your attached devices. Any time a connector is lose it can move around and while it’s not a threat because of a short circuit it does cause problems. When DC power is suddenly lost and reconnected, the surge upon reconnection can cause problems throughout the hole charging circuit and it could affect your battery as well. Charing circuits and batteries alike prefer to have power brought to them slowly at a steady rate and then build up the charging current as they control it. This is a common problem with dollar store bargains both in chargers and the cheap power banks. They use poor components and can damage your expensive phone.The only negative item here is the weight but this can’t be held against it as there is no better or lighter way to get this kind of capacity in one device. You could carry two power banks that each on their own might be lighter but there’s no advantage.~The included Travel Pouch keeps it protected and it’s got enough room to store a couple of USB charging cables as well keeping everything together in one spot.

I waited to write a review until I had to charge this bad boy. Mainly because I’ve purchased 4 or 5 portable chargers (in the $40+ range) and in time, they have all failed me. So far, the imuto is INCREDIBLE. I received it in the mail on February 28th, and I have used it literally EVERY SINGLE DAY. I charge my IPhone, AirPods, Juul (lol), etc... it just hit 0% today (March 19th). And I’m telling you, I used this thing EVERYDAY! I’m very glad I researched first haha! I HIGHLY recommend this device, I don’t mind the weight at all, if that bothers you then you might get irritated because it is very hefty. The appearance is also so slick, I love the colors and the battery percentage display, super simple.👌 EASY 5 stars. Thank You!!⭐️⭐️⭐️⭐️⭐️

I bought this battery for a trip to the EU to make sure I would have enough battery power for my phone, tablet and my dad's phone. It has worked well. It also "payed" for itself the day/night I got lost. I it kept my phone powered for 26 hours and it did not drop below 60%. For the peace of mind it gave that I did not have to worry about running out of power for my phone that I needed for GPS and Google translate made the money spent on this well worth it.

So I purchased this item and the BCM Power Bank 25000mAh Huge Capacity BCM Portable Charger Battery Pack Backup Battery Power Pack Dual Inputs 3 Output Ports with Intelligent LCD Compatible. The BCM state 25,000mAh hile the iMuto state 30,000mAh.The BCM is much lighter than the iMuto and it raised some questions. Batteries weigh. The more storage the more weight. So I tested both batteries. I charged a Samsung Tab S3 with a depleted battery while device turned off. This way, I could see the charge level and didn't have to take into consideration battery usage from a tablet sitting idle.The results didn't surprised me. The Tab S3 has a 6000mAh battery (on the sticky notes in the pictures I wrote 4450, I was wrong). The BCM managed to charge it twice before reaching 2% capacity.The iMuto managed to charge the Tab S3 4 times before I stopped trying. It went from 100% to 71%, from 71 to 42, from 42 to 13, and surprisingly, from 13 it went down to a flashing 3% for a while, but it completely filled the S3. After that, I stopped the experiment since it is undesirable to completely deplete a battery. This yield 24k mAh which is much closer to the stated capacity of 30k.The iMuto build quality, materials, and feel is much better.I give this product 4 stars. I have Anker power bank to compare as well but I like the display here which gives you the remaining percentage and not a bar of several lights to indicate capacity left. Over all, price to quality, this is a very good battery bank.I recommend

I wanted an affordable solution to power my two dashcams during parking mode without risk of draining my car battery. This power pack is perfect. Do not pay attention to the 30000 mAh rating. What matters more is the 111 Watt-hour rating. Use Watt-hours to calculate how long a battery can power your devices. I already have portable power banks for recharging phones and I'm sure this unit will serve that purpose well too. I am more impressed with its ability to power two dashcams for over 24 hours. It takes roughly 12 hours to recharge the power bank from almost empty with a 2 Amp USB charger. I plan to order a second unit and rotate usage while one recharges.

Tons of power. Ideal for long journeys.

This is a very good power bank for the price.Pros:- solid build / rigid- display that shows remaining charge is very accurate- 3 ports make it easy to charge multiple devices at once- as soon as device is finished charging, the battery stops sending power to the device so that it doesn't over-chargeCons:- once the power bank stops sending power, it doesn't sense that the device is draining and thus doesnt start charging it until u press the power button again.Hope my review was helpful.

It takes almost 1 to 2 full day to fully charge this Power Bank. I am already using a Fast Charge Cable. I am not sure if it is real 30000mAh. My phone has internal 3500mAh, and it was 23% when I go to sleep, plugged a fully charged 100% power bank to my phone and then go to sleep. I woke up 7 hours later, phone is fully charge but the power bank only has 53% left. I am still testing the product. I will constantly update this review.

Die Powerbank ist echt gut. Sollte einer mal den Fehler 188 im Display sehen:Das bedeutet Schutzschaltung. Leider hatte dieses meine Bank angezeigt. ( die Bank lädt so nichts mehr oder lädt nur noch eingeschränkt mit Glück. )Hab dem Support geschrieben und dieser wollte ein Video vom Fehler und ein Bild der Seriennummer. Gerät wurde getauscht ohne Probleme.5 Sterne für den Support und für die Leistung der Bank.Einziges Manko: eine Bedienungsanleitung fehlt komplett. ( hätte ich mir gewünscht um den Fehler zu erkennen ohne den Support anschreiben zu müssen. )Da die erste Bank fehlerhaft war ( nach einem halben Jahr Nutzung) bin ich gespannt wie die 2. sich macht.Sollte mir noch was auffallen so korrigier ich es hier ab.Wer fragen hat zur Leistung:Mein iPhone kann ich locker 5-7x laden oder das iPad 3-4x.Das reicht also locker für ein Wochenende aus! Dazu kann man wenn man Outdoor Freak ist ein solarpanel nutzen um die Bank zu laden.

So far it's been excellent. I use it regularly to charge a small Tab S, big Tab S2, and my cell phone. After charging all 3 from less than 25% to full I still had 35% power left. I bought it to keep my devices charged while traveling on my motorcycle and it works.Cons: It's too heavy for my wife's purse as an everyday charger and it takes a while to charge even with a high output charger. Neither of those is a problem for me though. My wife has a small power bank for her phone and I charge it while sleeping.
