Massive capacity, limited power output

I've been using this behemoth of a battery bank for the past while now with my Dell XPS 15 (9550) and have some preliminary thoughts on it so far.First off, this thing is a brick. I measured the unit along at about 1.2kg, heavier than some laptops now! All that battery capacity has to go somewhere I guess. The advantage of this is, it can pretty much keep my XPS 15 (another note, the battery bank comes with an adapter for the larger of the 2 Dell power plugs in use. My laptop uses the smaller one so had to get an adapter cable for it to work, but it works fine) juiced up for light use for an entire day, keeping the battery at a constant 90% (a setting I chose as the max level to charge the battery to to preserve its lifespan). You could be sitting in a library or something from opening hours to close with no need to be near a plug point if you're mostly just web browsing, listening to music etc.Now for the limitations, the battery bank is rated for a max of 3A at 20V, equating to 60W of power. My XPS 15 comes with a 130W power supply, and will consume that much while under a heavy load using the CPU, GPU and charging the battery at the same time. As such, the battery bank is fine to keep the battery topped up and not charging or gaming, or to charge the laptop while it is turned off. Once the laptop asks for a heavier load however, such as to start charging while switched on, or a game is fired up, this trips the overcurrent protection in the battery bank, immediately shutting it off. This is more of a safety feature than a flaw, but still makes it slightly frustrating to use at times. It would be nice if there was a way for it to tell the Dell laptop that 60W is all that is available, so the laptop can either charge more slowly or use a combination of port power and battery power while gaming. As it is, you have to turn off battery charging to use your computer while plugged in, or turn the computer off to top up the battery to full. Keep in mind, this only applies cases like mine where I am trying to power quite a high powered computer. Smaller laptops such as the XPS 13 which only come with I believe a 45W power supply would be completely fine.Overall, despite the limitations, I'm quite happy to have the battery bank available. It's better value for the capacity compared to the official Dell laptop battery bank (which admittedly does work flawlessly) while still being useful in quite a lot of applications. I don't see this being a must have device for most people, as battery life is generally good enough for most people on plenty of lower powered dual core computer out there that having a massive brick like this makes no sense to carry around. Even for me, it will likely serve as an emergency backup for when I really have to be on a long trip somewhere with no access to a power outlet (keep in mind, no flights for this thing! Too much Lithium I believe) while still trying to get a lot of CPU intensive tasks done (photo editing etc).

Disappointing

Very disappointed and frustrated with this. The power bank worked perfectly for about two weeks, but then began to just switch itself off even when fully charged. We have tried to contact the company numerous times, but have just been passed over to the "European lead" and have still had no response. As we are unable to return the item, or get a refund, this is all rather frustrating. Very poor product. Seemingly a waste of money. Would not recommend.

Purchased to Power Astro Imaging Equipment & Windows Tablet

I'm not one for reviewing products but I was so impressed by this battery I feel the need to share.I purchased the unit to power a Dell Venue 11 Pro 7139 whilst being used for astro imaging.On unboxing I was pleasantly surprised by the quality of the build, it feels solid without being too big of heavy.I've now run two tests with the battery powering the above tablet, USB 3 Imaging camera (with cooling fan), USB 2 hub, ioptron Smart EQ Pro & Nexguide II.I tried to keep the test as near 'real world' as possible with the tablet running Toupcam software imaging 7 minute exposures on a loop, Nexguide running (not guiding though) & Smart EQ Pro tracking running (with the occasional change of target)The ratings for the above equipment are as follows:Nexguide powered by 12v to 9v, 2A adapter (Nexguide rated at 150mA)iOptron Smart EQ pro rated at: 12V 0.1A(Tracking), 0.3A(GOTO)Both the above were powered from the 12v port on the battery.USB powered hub powered from the 1A USB port on the battery.Dell Veue 11 Pro 7139 (power supply rating 23.4W 2.0A) powered from the 20v port on the battery via the the tablet micro USB charging port (custom cable by me)The power discharge from the battery was nice & even, on each test it took approx 3 hours for each one of the charge lights to go out.I stopped the test (both times) after 11 hours with one of the four charge lights still lit (I didn't want to have to reset the mount home position when the battery finally ran out of power)For me this was a very unexpected result & very pleasing considering the price compared to a Tracer or Celestron battery of simular rating.The only (very small) gripe I have (which is the same as another reviewer noted) is the neoprene case is not side opening so you can't keep the battery in the case whilst it's in use.I will now aim to repeat the test on my CEM25P mount with the same imaging equipment connected.Needless to say I'm very happy with my purchase!Hope this helps you decide?

Very happy to have purchased!

Thiis is a seriously successful integration of portable power supplyechnology. It's not ridiculously heavy and holds its charge for ages - months! It fully charges overnight and probably even faster than that. Point is, I charge it much less than I use the device - and I use it a lot. Its countdown LEDs from 4 to 0 is a useful indicator to keep an eye on just how much charge you're taking out and about with you.Its multitude of delivery ports, voltages and adapters make this an ideal companion for most DC devices that might need an emergency charge without having access to a power supply unit. Solidly made, easy to use and comes with a decent protective case to hold all your wires together.This is one of those devices where I feel I made a great decision to purchase. Over 18 months down the line and still going strong!

Excellent versatile product

The 50000mAh power bank is a high quality product which is very versatile, I have charged two mobile phones, a tablet, two laptops and even powered a LCD monitor without any issues. I have been charging the power bank from a off grid 320w solar panel which only takes approx. 5-6 hours, then lasts for 1-2 days with the monitor on for at least 8 hours per day. This product is compatible with so many electronic items I will probably invest in another one before too long, I would highly recommend this excellent product.
