XT-20000QC3 Powerbank Modern DC + USB QC3 Battery with 20100 mAh - 1x USB, 1x USB QC3 and DC Connection from 5 to 24 V 65 W Max. - Power Bank for Laptop, Tablet, iPhone, Galaxy, etc.

This is an excellent unit, very versatile, I've tested its capacity and its a little off the 20100mAh, nearer 12000 but I would still recommend it as still has a lot of capacity and is great for charging a laptop as well as the standard 5v stuff. It charges my HPx360 fine although you need to set it to 20v (not 19v), also use the correct adapter otherwise you may fine it wont charge but will still run it. Its compact and not very heavy so a great all round backup power unit.

Been happily using the older model XP-16000-QC2 for over a year. Brilliant product that has helped me in many situations from powering LED lights, charging laptop, power controllers in the field ranging from 12-24v. Thought I would treat myself to a newer model with higher capacity however after charging a pair of bluetooth headphones it failed about 5 minutes into powering a 24v 0.65A mbus level convertor. The button does nothing on the side, no power output from usb or barrel jack. It will not charge by USB on many chargers I have from 5v 1A-2.4A and a few laptop chargers that all work with the old model. Looks like a faulty device so will see how the customer service is in response to this review. Update: Amazon refunded the money and I bought another one. A few weeks in and it's still working. One of the most versatile power packs on the market. I definitely recommend.

Does everything as described. One oddity which may not be due to this product was that when connecting to a mains socket with integrated usb charging point the powerpack shutdown after a short time so did not charge. Now this pack does have an auto shutdown feature when the input draw on recharge drops below a set value, but I saw no difference on the charging draw shown on the display between using the integrated USB charging point or a plug attached USB charging adapter, which worked fine. It’s possible it may just be due to the Integrated USB mains socket circuitry. Charging Powerbank with a laptop power supply (19v Toshiba) worked fine and was as expected faster than using usb recharge, but fast recharge is of course not as kind to the batteries longer term. There is another version of this powerbank from XT-Power which doesn’t have the auto switch off so can Power very small draw devices as well.

Surpassed my expectations. I've been using this for 5 months, and mainly bought it for my Lenovo Miix 520 hybrid laptop / tablet, which I love but has poor battery life, and also can't be charged via USB; 65W DC mains adaptor only. (I also had to buy an adaptor head for lenovo's socket size - see photo - 4.0mm x 1.7mm Male to 5.5mm x 2.1mm Female). All the other products I found were very bulky and provided a mains socket, meaning you'd need to carry the laptop's mains adaptor along with it, were 3 star rated, and around twice the price. I also obviously didn't want to carry a separate charger for my phone, or its wall charger as well, so wanted something to cover all those bases. This does the job perfectly. It holds its a charge excellently (seems roughly around what they state, maybe a little less), remembers the voltage you set it to (20v for lenovo miix) which I'm really glad about because setting it every time would be an accidental too-high-setting waiting to happen, and the display is handy for seeing how much power your device is actually drawing. It also actually manages to charge my phone and tablet faster than their wall chargers: I was never able to use my old Samsung Galaxy Note 2014 tablet while charging and still have it go up before, but now I can. All round, great product.

Sadly I had to return this item as after three weeks it failed & no longer worked at all

I got this for my remote camping trip to Iceland, ! where there would be no power or running water , so real wilderness camping, i charged it with a solar panel, and use it to charge my phone laptop and camera gear. I also used it with a small inverter to power my camera charger and laptop charger, Had no problems and the selectable voltage is useful for other appliances

Works well, It hasn't been used many times but when it was it handled my requirements very well. I used it to drive my telescope mount, It ran for a couple of hours and dropped the charge by less than 20%. I particulary like the %charge indicator and the fact that I can charge from a USB charger if necessary. The real test of course is how long it remains fully functioning. So far so really good.

Perfect fit for mpc live

This is an excellent powerbank. I measured the capacity myself at 15000 mAh or 55 Wh. So that an efficiency of 75%, that good enough. The only downside is that this powerbank has no usb-c, something that is unforgiven at this point (it being from 2020). Screen is nice, seing the wattage is great. Recharging with a laptop adapter goes really fast (one hour). And it can deliver high aperage to devices that need it without issue. Works excellent with the MPC One, with the included cables. Also works great with film lamps.

ich hatte mir diese PowerBank gekauft, weil ich eine Stromversorgung für meine mobilen Funkgeräte benötige. Mit der Powerbank habe ich nun alles, was ich brauche: einen Stromlieferanten, verschiedene Spannungen, ausreichend Strom für den Betrieb und für das Laden der Akkus, und auch des Ladegerät ist „eingebaut“. Damit ersetze ich einen LiFePo-Akku plus Ladegerät. Der Preis ist angemessen, verglichen mit eben einem Li(Fe)Po-Akku und dem Ladegerät. Ein Artikel in der Zeitschrift „Funkamateur“ machte mich auf das Produkt aufmerksam.

I'm using this to power my piano keyboard which is on a stand with wheels. So this together with a midi bluetooth transmitter allowed me to go wire free. The only issue I had was that with the different converter adapters that come with the product, there is no way to reverse polarity, so I had to cut the cable, re-wire and put a shrink wrap on to make it work with my keyboard. That could also be solved with simply buying a different cable.

Parfait pour MPC one Excellente autonomie Simple à utiliser Je recommande

Utile, affidabile e robusto, puoi usarlo per alimentare o caricare una svariata lista di apparecchi tra cui pc, smartphone e nel mio caso una montatura eq o una camera raffreddata zwo, un acquisto veramente azzeccato.
