It works, but the build quality is hilariously terrible

Reviewed in the United Kingdom on 22 June 2015

I use rechargeable batteries in my flashlight at work and I normally use the extremely high quality Ansmann 16+ charger. It's probably the best there is, however due to its size it's not that portable. I usually recharge my batteries when I am sleeping as the charger sits on my bedside table. The 7dayshop USB-powered charger looked interesting as it would let me charge AA and AAA batteries from a PC, which I have access to in work. I also wanted to try it with my solar powered charger that allows any USB items to plug into it. I have used 7dayshop batteries for years with no issues, so I assumed that the quality of their charger would be reasonable.

The 7dayshop USB-powered charger arrived quickly and appears to be made from the cheapest quality plastic available. It feels horrible and looks like a toy from Poundland. Surprisingly, it does work; I put in two batteries and the 7dayshop charger correctly registered that one battery was flat and the other was fully charged. However the build quality is so poor that I wouldn't leave it unattended.

On average, it takes about 5 hours to recharge 2x AA batteries from flat to full, based on a USB 2.0 port producing 0.54A.

Energiser used to make a USB-powered charger for AA and AAA batteries, but that charger seems to be no longer available. There is a similar product from Portapow, but I bought one and they don't work at all. Ansmann and Duracell still don't make USB-powered battery chargers.

I resolved my issue by purchasing the Ansmann 8+, a smaller version of the Ansmann 16+. These two chargers both have a dedicated "precharging" cycle for dead batteries and they can charge AAA, AA, C, D and 9-volt batteries. It's still pretty big, but I can keep it in my locker.

I was very happy with this when I first got it because it was good value. It charged quickly and came with lots of adapters. The main downsides were that it was difficult to read the display and the instruction leaflet was an unrecognisable collection of english-looking words. However after 10 months of weekly usage it started flashing all 4 lights on certain batteries (the four batteries are supposed to gradually light up as the battery charges). I thought the batteries were faulty and bought new rechargeables but it kept disliking certain batteries and the instruction booklet was no help. After being let down by batteries that were apparently charged on two occasions I have given up with the machine and bought a new Energiser recharger which plugs straight into the wall (seems okay so far). So, I'm fed up that the recharger does not work properly and I have wasted money on new rechargeables that were probably unnecessary but I do still have a USB/Plug adapter.

Simple but effective charger

Reviewed in the United Kingdom on 17 April 2012

Other reviewers have commented on the lack of clarity when charging is complete. This really isn't a problem and, as a true bloke, I'd plugged it in to the 12v supply on my narrowboat & it was working before I thought to read any instructions.
I'm not sure how effective the "discharge" cycle is. After an hour it was still apparently trying to discharge 4 batteries which I thought were flat. As modern NiMH batts are less susceptible to false discharge memory problems I'll probably not use this function.
Along with other fast chargers it doesn't like batts which are less than perfect - I'm still looking for a 12v trickle charger that will charge these, of which I have a few.
But it works & it's good value.

This charger charges 4 batteries at a time and can do multiple sizes such as AA and AAA. It comes with a car, USB and mains charger. It charges fast and has a display to show you the progress.

My only complaint is that it came to me with one piece that touches the battery end, in the charging chamber, bent and weakened. It still works but I have to manipulate it before I use it or that one battery won't charge. Eventually it will break off. I took one star off for this although it is likely a random defect.

It does not come with batteries. Buy an extra 4 when purchasing your batteries so you always have some. I bought two packs of the 7dayshop 4 battery pack of AA batteries for this charger.

Quite good but ignore charging times

Reviewed in the United Kingdom on 6 May 2011

I read the other reviews before purchasing this charger. I'm still fairly pleased with the charger but cannot say that I've managed to recover any of my un-chargable batteries BUT THAT IS NOT THE FAULT OF THIS CHARGER. Small, neat, doesn't get hot (like some of the other chargers I've used). Main gripe is that the suggested charging times are completely wrong. A single 2300 mHA battery took 8 hours to charge, a set of 4 new 800mHA batteries took 6 hours. This could possibly be a positive aspect of this charger as it implies lower charging currents hence no heat and less chance of damaging/stressing the batteries. Would I recommend this charger? YES (as long as you're not in a hurry)

Cheap to buy, but works perfectly

Reviewed in the United Kingdom on 8 June 2014

I've been using this thing for a couple of years now as a charger for my keyboard and trackpad batteries and it hasn't let me down.

It charges quickly, has an indicator to let you know the state of charge and is also small and unobtrusive. It has a USB connection so I presume it can be powered from a USB port, but I have never done this - I use the included power supply instead which is rated at 5V, 1A, which is pretty much what you'll get from most USB ports these days so I assume it would work fine if you wanted something you found run off your laptop if you were away from home.

Best charger I've owned

Reviewed in the United Kingdom on 3 September 2013

Verified Purchase

When I saw the details of this charger it seemed too good to be true. However after reading the reviews I found that most people had rated it as 4- or 5-stars, so I bought one.

I wouldn't describe it as "super fast" but it does an excellent job of discharging and recharging my batteries. I do a lot of geocaching and use up batteries quite quickly. This is the first charger I've owned that prolongs the life of rechargeable batteries.

I like it so much that I've just bought a second one to keep in my caravan so I don't have to remember to pack it each time I go away.

Recommended.
