HiQuick 2-slot 9V Battery Charger, Fast Charging Function, Type C and Micro USB Input, with 2 x 280mAh 9V NI-MH Rechargeable Batteries, Battery and Charger Set

I took a chance buying this after being told TENS machines cannot use rechargeable batteries and happily I was correct and this works with the TENS and lasts ages. Delighted.

I used a Medi-Fit 3 TENS machine to manage the damaged joints and spinal damage I have. This machine uses one 9 volt battery a day at £3/4 each this machine is saving me a fortune. It's easy to use and takes a few hours to charge two batteries so I've always got a spare ready to use.

GOOD CHARGER UNIT AND GOOD VALUE WITH TWO BATTERIES , + AND - MARKERS COULD BE LARGER / DIFFERENT COLOUR MORE PROMINENT ON UNIT .

Arrived promptly, in good order and as described. Very good value for this charger with two rechargeable batteries and they charged up well using my mobile phone USB charger (1.5 amps output). It comes with instructions which says to use the included USB cable with a charger with a minimum of 1 amp output. If you don't have a mobile phone charger like me then a charger for your Chromecast or Amazon Fire Stick both have have 1 amp outputs so should be ok. Nice to have the auto cutout when the battery indicator shows fully charged, and it can charge either one or two batteries including Lithium rechargeables as well as the NI-MH type that comes with it. The details state that Lithium rechargeables are charged at about 3 times the charge rate so higher powered Lithium batteries should also be a quick charge. Both the charger and the batteries look high quality which is more important for rechargeables as obviously they're reused many times so need to last a longer life than throwaway alkaline batteries. I've only had this a short while so can't speak about there long term use, but I guess that's always the way with this sort of thing and so far so good. I'm very pleased.

Included batteries were only half charged but I expected that. Charge time was surprisingly fast. Ideal, cost effective solution for active bass guitars when you accidentally drain the battery by keeping the cable plugged in!

Works well just what I needed

Lights up and charges the 2 included batteries from USB. It goes into trickle charge when its done, so it won't cook or drain.

These batteries and charger are good value. However, I use them for a cat deterrent alarm (an RSPB approved one). Unfortunately I have to recharge every week and they take 6 hours to recharge, so I'm going to look for better and higher spec lithium ones. Update: The company fully refunded me, I found them to be kind and helpful. Thank you.
