I only have a couple of Anker products, but been pleased so far with a small power bank and some cables.Thanks for all the good tips in this thread. Ordered myself an Anker powerbank from Amazon after rereading this thread. Seems like very good quality for a very good price.
I have the TOMO "V8-4", it's actually a pretty old product. I found an old piece of paper which i kept for its written contents but I am cleaning the room and it's really time to toss it. Before doing so, i am transferring the data, here we go, now for our common records:I have a TOMO model power bank and use it with reclaimed 18650s. It holds up to 4 cells, easily slides open so serves as a 18650 battery charger as well. has two USB outputs and mini USB input. It's not super rugged, but has LED display for each battery to show power level.
I've found a good way to check micro USB cables... I plug them into my phone and see if they can activate fast charging mode the ones with smaller wire that can't handle 2A often won't fast charge. I've found a surprising source of micro USB cables.... Dollar Tree. So far all their cables support fast charging even the extension cables support it so you can hook 2 cables to make a 6' cable.
I forgot to mention that I found some LED lighted cables at Dollar Tree which also work fast charging (Qualcomm 2.0). However I don't like the way the cable lights up the ends are super bright blue bindlingly bright.The aforepictured pink cable (so it's easy to see in the dark) is 10'.
A USB cable technically only needs to handle 1.5A to meet the standard, but recent iPhones and most tablets will charge at 2.5A, so don't skimp on the cable if you want the speed.
New toy: Soonhua USB charger monitor, now I can spot defective cables/use the cable with least resistance every time. The display is live, updates ~twice a second, initially shows alternating voltage and current, until voltage stabilizes and then shows current until charge stops. Turns out an iPad that is charging and playing a game cruises at 2.5 amps, an iPhone usually hovers around 1.5 (the phone taking the picture is plugged in here,) AirPods need only .25..
