Docooler Tomo M2 18650 DIY Power Bank Compartments Battery Case External USB Charger with Intelligent LCD Display for Phone Pad Tablet

This is brilliant. It charges my Samsung Mini very fast and so handy when I am out and about and my phone battery is low.

Nearly 5 stars but drops a star because its a slow charger more like 4.5 stars. Mine arrived and worked no problems with batteries salvaged from a old Anker power bank that had stopped working, turned out the batteries were fine but the electronics of the tanker unit were at fault but I'd had it for several years. The Docooler Tomo M2 is very useful as a charger of 18650 batteries as well as being a power bank, the only fault is it charges phones etc very slowly as each one of the cells has a dedicated USB output, so once one 18650 cell is drained you then have to replug your lead in to the other cels USB output. For the price this is very good value and if you have a few 18650 cells hanging around this is the perfect combo of charger and power bank. Its a good small size and very light weight, It should be quite durable. I'm thinking of buying another.Caveat I've only had this for 3 days but have done several charge cycles.

Whilst the product looks good and has good build quality, it gets very hot and the batteries run out far to quickly charging the Iphone only once, the same batteries in different charges give multiple chargers to an iphone. Very badly engineered !!!
