Fast charge is great.

Battery Capacity: 20000mAh | Colour: Black

I bought this power bank to take on a multiday tramp with family, mainly to charge phone for use as a camera, but also our watches and headlamps. In the end we only charged one phone and 3 watches because everything else lasted the distance so I could have got away with a lower capacity powerbank because to be honest, this unit is bulky and heavy. However, we now have a good quality powerbank to use at home going forward and for the price I paid on special, it was awesome value for a quality built unit and the fast charge is super handy.

Fantastic product, don't overlook

Battery Capacity: 20000mAh | Colour: Black

This is the second one I do get. The fast charge at 18W is solid and it will not let you down. It has a smart system too but just in case I do advise to use the slow charge with small devices.
I have successfully charged 3+ times cellphone batteries with avg of 6k mAh. For the price, this one is one that you should look into getting one.

Value for money purchase

Battery Capacity: 20000mAh | Colour: Black

Not used as yet, initial charging took four + hours, my partner was going to carry it in her purse for emergencies but too heavy so it now sits the car glove box. Overall happy with the price paid.

Perfect for my on the go video recording with my phone

Battery Capacity: 20000mAh | Colour: Black

This power bank charges my devices faster than I as expecting. I shoot a lotf video clips out skateboarding and often run my phone out during a session. I plugged my phone into the powerbank when it was on maybe 20%, while video recording , thinking that I would need to keep charging it while I drove to find that it had fully charged the phone even while running the recording - so good! Also, it has great capacity. I completely charged my phone maybe 3 times and still had over 50% capacity on the powerbank Very happy with my purchase, and price seemed pretty reasonable. Win!

Great value and convenient!

Battery Capacity: 10000mAh | Colour: Black

My first powerbank, so can't compare. But don't have any issues. Plenty of juice, dual input/output is awesome, it's a good size and the best value I could see with a quick look around

Ok

Battery Capacity: 10000mAh | Colour: Black

It holds a lot of charge. It can recharge my phone numerous times on one charge, so it's great for camping or long power cuts (eg have one for your earthquake kit). But I wish I'd bought a charger that worked wirelessly.

Great value

Battery Capacity: 10000mAh | Colour: Black

As others have stated, 1st charge takes about 8 hours but works great, I bought to replace a Mi 20000 that we had for many years which suddenly stopped working
So is smaller & lighter
At this price you cant get better, great capacity & 12 layers of protection for peace of mind
Fast shipping as always
Very happy with purchase
