Fast charge model from Ocoopa. My model charges slower which might be gentler on the battery. Actually the real reason I bought the slow charge model was it was cheaper

Amazon seem to sell the model I have and amazingly it’s still £25!

Story

During OggCamp I mentioned to Ken that I had an electric hand warmer and he asked me if it was any good. He suggested I do a long term product review of it. So here is my review

I do lots of dog walking and suffer from cold hands.

I've had different hand warmers over the years:

Ones that you boil in water. Don’t last long
One that is activated by removing from its packet. Lasts for many hours actually too long. They seems very wasteful as they are single use.
Zippo hand warmer works well but is a faff to setup and sometimes goes out.

This electric hand warmer is by far the best solution I've found.

It saved me twice during OggCamp as I used it on two occasions to top up my phone. When arriving and leaving OggCamp.

This was the first time I’d used the hand warmer to charge anything. I was very glad it worked.

At the time of purchase I was rather sceptical about the whole idea of electric hand warmers.

The batteries are not used in ideal conditions. They get very hot and when in use a lot of current is drawn from them.

My Hand warmer is now almost 4 years old and is still going strong with no noticeable degradation in capacity.

It has a rated capacity is 10,000 mAh. The highest charge it achieved was about 1 year into use. It accepted 8034 mAh of charge. I haven’t checked again since November 2021. However it still continues to last many hours / multiple dog walks.

I always get a bit nervous over the summer months as it is left for a number of months unused. Luckily living in Scotland I don’t need to wait long until the weather gets cold. Did I mention before about the horrible weather in Scotland?

How I look after the battery

Always wait for the battery to return to room temperature before putting it on charge.
Don’t leave the hand warmer for more than a few days at 100% charge.
Try not to completely flatten the battery. If you do flatten the battery then charge it up soon afterwards.
If storing it for a number of months then try to store it at approximately 50% charge.
