I bought this ...pack to replace a 4.5Ah sealed lead acid battery I had on a garden spray trolley. I wasn't expecting this to last as long as the original battery (although it is rated at 6800mAh) as it's about an eighth the size, and I have experienced exaggerated claims over lithium batteries from other sellers. Well, this thing is great, pushing water through a 60psi pump up to heights of around thirty feet is no problem. My trolley should last 2 hours continuous with the 4.5Ah SLA battery, I used this today for in excess of 2 hours and checked the voltage at the end, still at 11.66v, very pleased, may even buy another one as a spare for longer spray times. The only downside I can think of is the recharge time, charging at 1/3 of an amp from dead suggests a 24 hour charge time. That said, for my requirements, and the way in which I use the pack, it will never get that low, and in the time I've had it (I use it most week days) it's only required a couple of hours top up.

This product seems to be well built and so far has worked well.... The price is also very good. However when the writing on the box is very bad English and full of errors, and this is also the case with the sheet of paper included with instructions for use, it makes me a little nervous, given the bad reputation for lithium batteries and safety. The charger supplied is as shown in the picture, i.e. not a UK plug, so you'll need an adaptor. Although it arrived charged and ready for use, it takes ages to charge - that is, if the badly written instructions are correct and you need to wait for the green light to go off. Still waiting many hours later. As you can see in the picture, the supplied lead is very short so this battery needs to be placed close to the item it needs to supply. WIth hindsight I would have preferred a battery with a charge indicator. The red light is either on (working) or off (flat). The legend on the battery itself are incorrect. It says: USB. LEN. DC IN/OUT. OFF/ON There is no USB connector. LEN should presumably be LED. Makes one start to think this product has been thrown together, with no quality control. Which is a worry.

Cheaper than other similar products. It has only one type of o...utput: DC. If you want this only, then good. No power level indicator of any type Instructions are confusing: the pack needs to be switched on to be charger!?

I bought this one to power supply my BlackMagic Pocket Cinem...a Camera. It works fantastic. Fast, reliable and high capacity! Much better than powerbank.

Very neat package. Eventually worked out that when sett...ing to charge, the switch has to be in a position that the green light came on. Powering a 300mm LED striplight it seemed to last around 24 hours, which is more than adequate for our purpose. Advice in whether it can be taken on a plane would be helpful.
