imuto Upgraded 27000mAh USB C PD Power Bank, 30W Power Delivery Quick Charge Portable Charger with 3 Outputs External Battery Pack Compatible with iPhone 13, Samsung S21/S20, iPad Pro Huawei and More

These Imuto powerbanks are really decent in my limited experience.I got one in April of 2020. Still working well. As a busker they are Super useful for powering outboard sound equipment. The X4L 20,000 mah was good for about 9.5W max.So went for this one with a bit more power available. If i can pull 18w (12v @ 1.5 amp) from it via USB C, to power a halogen bike light, i'll be happy.So far so good.Arrived @ 85% as to be expected.Charged for a couple hours, and then charged my Samsung s6.Used only 4% of the powerbank for a 75% charge. (Tbf my phone battery needs replacing as its only @ about 70% of design capacity).Imuto are starting to make a decent name for themselves.Update April 2022:-Original powerbank bought in 2020 (X4L) still doing well.Version in this review (27,000 mah) is an absolutely quality purchase.It puts out 28w max consistently for about 3h 40. (powers a 35w halogen light for 3h 56 mins total (to be exact lol ;)) In nominal thermal conditions (i.e room temp).Battery is slightly over-capacity and is about 110% of rating. So just be careful if you are going abroad as it might just be over Watt/KG limit. To me this is not a downpoint, and you are getting 10% more than expected.Busking utility:-Easily powers a 10w Kustom KGBAT10 guitar amp for about 80 hours on a single charge.Powers a 40w behringer mpa40bt loudspeaker to about 60/70% volume.Reccommend. 5/5Update Sept 2022*Powerbanks still operating well so bought 2 more X6CSTested 1 for almost full discharge on a 28w/h load. 3h53 with 18% remaining.Other one was tested for a couple percentage points only, and power output was 2m57 @ 28w per 1% drain. Which tallies with the other figures and is approximately 110-116 watts total energy per powerbanks.So 450w for just over £100 is not too shabzi in my opinion.Max power out i've had was 15v @ 2.93 amps..around 42w. Didn't try longevity test at this voltage, just a brief test, as it was technically over the power rating of my 12v bulb and i didn't wanna blow it.Longevity test as aforementioned (28w) was performed @ 12v.Hope these technical stats help people make their own considered decisions.As long as ya don't get a duff-one (i have sadly read some negative experiences) these powerbanks are exceptional.Update August 2023:-A correction to my previous maths and specifically wattage used/capacity.When using the powerbank with a halogen lamp, i was anticipating the previous wattage numbers i did, based upon the voltage settings being a defined amount. I.e green light = 12v, blue light = 15v. The amperage i was measuring with an ampometer. I.e it was fully known = 2.43A max. I measured the voltage with a voltmeter, and they were giving accurate readings, however these were admittedly passive readings.Since attaining a usb power-reader i have now ascertained that the voltage although registering as 12v, 15v by way of the colour light that is illuminated on the USB PD convertor board, is actually dropping to around 8.83V max when under load. This works out to a max peak/consistent power output of around 21 watts/hours. You will not get 40W+ out of these as i had previously written. Nor is the capacity as high as i had previously calculated.I have run a couple tests recently and i've had 80w/H @ 8.8V & 2.3 Amps. I.e the lamp stayed lit consistently at approximately the same level for just over 4 hours. Which regarding time frame is about the same as when i first tested them a while back.One point of concern is that one of the latter units i bought in Sept 2022, seems to of partially failed. (it's down to about 50% capacity) the other 3 are still at or close to max capacity. I'm guessing this is likely due a faulty cell and will be contacting Imuto regarding this as it is still within the 1 year warranty period.Anyways in the itnerests of transparency i hope this helps someone out there.All in all i would still say solid powerbanks and very happy with the purchases.Will try to post update on return process.Highly recommend.

I bought another power bank on ebay before buying this one and was a fake.It stated 27000mah or roughly 100watts but the capacity was one third of that.I performed the same test on this powerbank and as you can see on the picture it really has the stated capacity.Charging speed is not amazing but 18W is good enough for a mobile phone if you are not in a rush.This power bank recharged an Ipad Pro from 0 to 100% plus my mobile a few times. I measured the charging current and it reached 85Wh, which considering the losses, is another indication that the capacity is really the stated one.The ONLY downside is the led indicator during charging, which will go up to 99% and stay there for 3 hours until it reaches 100%.Recommended product.

Absolute rubbish and unbelievable considering how much it weighs.Worked ok for a few months but even then once it got to fifty or sixty percent it was actual empty and the counter drops to zeroNow it just goes down very very slowly and actually proves no chargeDon't buy this or products from these folks

In total I have purchased four "imuto Upgraded 27000mAh USB C PD" branded power-banks. I use them for a specific purpose - powering two cars dash-cams for 24/7 use. This saves the cars main 12V batteries, which would previously give low-voltage if unused for several days.Each battery will power a dash-cam for approx 4-days continuously. I have a routine where I change them during Sunday & Wednesday evenings. The batteries take around 9-hours to recharge from empty to full. These dash-cams have saved both my daughter and myself during previous insurance claims. Everyone should fit a dash-cam.Using a cheap "USB Safety Tester", I verified that each battery outputs a little over 28,000mAh. This is rare because capacity is actually HIGHER than manufacturer specs. Most other brands overstate true capacity.These power-banks are quite large and heavy, so do not expect to carry them around in a jacket pocket. The 0-100% battery indicator is also rather inaccurate, but this is normal for all power-banks.Overall, the best high-capacity power-bank I have used so far (and I have owned many).Edit: After 2-months ownership and approx 8-10 full charge/discharge cycles each, all of my power banks continue to operate at full-capacity. The remaining battery-indicators continue to be inaccurate, with some dropping from an indicated 100% to 0% far faster than others. However (and this is the important bit), all give the same excellent real-world capacity.Below shows indicated capacities from 4x identical batteries after 4-days usage when connected to continuously-running same-model (Yi 1080P) dashcams.Powerbank, Starting capacity, 24-hours, 48-hours, 72-hours, 96-hours.#1, 100%, 82%, 63%, 45%, 0% (still running)#2, 100%, 90%, 81%, 62%, 1% (still running)#3, 100%, 84%, 68%, 50%, 12% (still running)#4, 100%, 73%, 40%, 11%, 0% (still running)After 4-days, each battery is still running, but holds very little remaining capacity. They'll probably run for ~100 hours given my specific dashcam application.In-summary, great powerbanks - just don't trust the remaining capacity LED. One of my batteries shows nearly-empty when it has almost 50% true capacity remaining. Perhaps I got a faulty batch as all were ordered at the same time.

Bought 2 of these- one suddenly went from 40% to zero - in fairness it was very cold. The other one didn't drop suddenly. Hot a lot of phone, tablet, earphone, camera charges out of them.

I received this on time and it had 80% on it. I charged my phone twice, my wife's phone twice, her Ipad. It took about 2 hours to charge my Samsung A50. It is a bit heavy but we'll worth it. It will last a whole weekend. It does take about 8 hours to charge up. I like the percentage on the screen and it only comes on when it is charging. Well worth the money and I recommend this product.

Plenty of juice to charge anything. Takes a while to get charged up but holds the charge for months.

Batteriet har stor kapacitet men går inte att ladda med modern laddare 20W så laddningen tar lång tid med gammal laddare och är väldigt tung att bära med sig så den ligger som reservbatteri i bilen.

Super

Consegna e condizioni prodotto perfette.Il prodotto si presenta subito di buona fattura ed elegante.In dotazione un cavo USB-USB c.Unica cosa che non mi aspettavo è il peso.È molto pesante! Quindi non adatto a chi cerca qualcosa di comodo e tascabile.Piuttosto lo consiglio per chi cerca un prodotto di ottima qualità e potenza. Così da garantirsi diverse cariche senza avere sempre il pensiero a ricaricare il powerbank. Inoltre il piccolo display con la percentuale di carica è comodissima, molto meglio del sistema "a spie" di altri prodotti concorrenti.

Håller till flera laddningar men den slutar ladda hela tiden så mam får starta om. Rekommenderas inte.

Ottimo power, resistente, durevole e con ottimo carica che dura tanto. Ovviamente è un po' pesante ma é normale
