TECKNET Power Bank 10000mAh, Ultra Slim Port Portable Charger Dual Output External Battery Pack Compatible with iPhone, iPad, Mac, Samsung, Smartrtphone and More

Had this for about 2 years. Used maybe 40 times? Only ever for emergencies and in my travel bag. Other day i seen the battery had expanded within the case so no longer fit for purpose. Still works but not safe

The TECKNET Powerbank performs just as expected, continuing to accomplish customer satisfaction. I was very pleased with my old Anker PowerCore but unfortunately I've lost it. Now this Powerbank is the perfect substitute!The Powerbank takes probably around 5.5h to fully charge from empty which is way outstanding for a battery this size, considering the Anker PowerCore takes 12h. You can charge multiple devices with efficient power delivery and there's also a pass-through which is a nice to have in order to charge your battery while charging devices. I can easily charge my mobile 4 times before recharging again. This makes it very helpful for me when commuting and going for a trip, I even sometimes help my colleagues juice up too. The LED indicators will make it easy to know when a recarge is needed.Some people think this is bulky or heavy, but believe me, the form factor and the weight is just on point. You can put it in the pocket of your jacket or regular jeans. Having said that, I normally put it in my backpack with a cable long enough to have my mobile comfortably on my hand. The quality of materials is more than adequate, this will surely last countless drops and knocks.The battery has proven itself reliable after countless times charging and discharging. It is probably difficult to tell if it has actually lost any power without special equipment, for me it it still charges my mobile 4 times no problem.Even if you were to feel like it has lost power, the 18 months warranty would cover that.Tecknet has amazing customer support and would sort out any problems in the blink of an eye. I have never had any problems with their products or service.Buy with confidence, recommended product!

I got the TeckNet power supply for a few reasons. It has Power Delivery and over charge protection for my iPhone and Samsung phones, it has two 2.4 amp outputs so I can run my Raspberry Pi 3b and it can charge up 20 000 mAh in 4 hours. The first thing I did was to test all this and it pretty much lived up to all the promises.Using a USB to lighting cable my iPhone X charged in no time at all. I also was able to run my Raspberry Pi for over 8 hours as a Kodi box playing movies without issue. Lastly the charging of the battery, after I had flattened it, it took only a bit longer than 4 hours to charge it to full (4hours 40mins or so) but that could be due to my old USB C charger. I have not done the maths yet to check if the power socket adaptor it is delivery enough power to the battery.One thing that was not great is the 4 little lights that indicates the charge remaining level. When you are dealing with a big battery like this you would hope for something like a display with percentage levels. A very small gripe about a great battery.All in all, this is a great little battery. It weights about the same as my previous 20000 mAh (. I don’t think any battery with this much power could ever be light) but its dimensions are smaller. So, if you need a lotto of power on the road this is a very good option, and while it might fit in your pocket, you probably want it in your bag.

This powerbank is great value for money. I always used Anker powerbanks but if you want same capacity with this one it's over 30 pounds. On top of that this one has more features.It's great for long travels or if you have a family so you need to charge multiple devices at one on the go. It's not light by any means however considering the capacity and metal case it's expected. I bought this so I don't have to worry about finding a lead to charge during my 1-2 week trips.I think it looks bigger in pictures. See pictures compare to Note 9It has latest Quallcom quick charge 3.0 for rapid charging. 2 USB-A ports and 1 USB-C port for charging your devices. So you can charge 3 devices at once. You can charge your powerbank with micro usb or usb C port. It has all circuit or current protections in place as expectedThey provide short micro usb as well as usb c cable which would cost few quid on its own. However they don't include a pouch for the powerbank which is a shameIt has metal casing (compared to Anker plastic) around the site. The bottom and the top (where the ports are ) are a bit rubbery textured material. It has curved on the side for better grip.Overall I think it's good value for money and I would definitely recommend it

The first thing I noticed about this power bank was it's weight. It's not a lightweight unit, but that is compensated for by its good solid build and feel. It's not over heavy either, but may be an issue for the odd purse!!It is an up to date unit with USB-mini and C connections for charging it and two USB outputs for charging devices.I connected my Huawei Mate 20 Pro to charge, (which has a 4200mAh battery) and it went up from 43% to 68% in the space of half an hour which is pretty good going for any power bank. Other phones would probably get charged more as they are smaller batteries.The blue leds on the side indicate how charged the power bank itself is and when it is being charged.There is a power button to turn the unit off and not waste charge.With 20,000mAH of power, this unit will no doubt be very useful on travels and days out with the family, where everyone will probably want to charge their phones after taking photos etc.It also comes with an 18 month guarantee extendible to two years if you register the product, so you can't really go wrong!!
