The TalentCell unit looks useful for anyone needing to power multiple devices; it has some good reviews (but also some pretty bad ones).
I noted that the TalentCell mini-UPS comes with 2 DC cables, but they're both fitted with the 5.5mm o/d x 2.1mm pin plugs. In the sales blurb on Amazon they state "if the size of your device input port is not DC 5.5 x 2.1mm, you need to buy the proper chord or adapter separately.". In my experience that means "go find one" not "we can sell you one". I went to the TalentCell website, but couldn't find any mention of available accessories (or indeed of their mini-UPS!).
It's always worth checking directly with the supplier to make sure the UPS comes with either a cable or adapter that fits the BT Smart Hub. Most (if not all) have the "standard" 5.5mm/2.1mm plug on the end of the DC power cable, so either a replacement DC cable or an adapter is necessary. You'd think it would be pretty easy to get hold of a suitable adapter, but although there are many adapters out there very few accommodate the 3mm pin in the BT Smart Hub 2 DC input socket - the correct plug size for the SH2 is 5.5mm o/d x 3mm pin; a plug sized at 6.3mm x 3mm pin will also work, although it's a tight fit (I've also successfully used a plug described as 6.2mm o/d x 3mm pin, but I believe the 6.2mm and 6.3mm are actually the same - mine both actually measured 6.25mm. The adapters all need to fit onto the 5.5mm x 2.1mm pin DC supply cord plug. Issues I've had in finding the correct adapter are:
- Supplier of my original UPS included a set of 10 adapters, one of which was the 6.3mm o/d x 2.1mm pin item. I recently bought a second identical UPS but the supplier no longer includes adapters; I was advised to look for a third party supplier.
- The correct plug is sometimes described as a Philmore 206, but the manufacturer of the plugs doesn't make adapters (and is out of stock of plugs, although I'd prefer not to rewire anyway).
- I did find an adapter set identical to the one originally provided with my first UPS, which as stated had the 6.3mm o/d x 3mm pin included - but it's an expensive way for a single plug.
- I've seen some small UPSs that specifically claim compatibility with the BT Smart Hub 2, which is probably accurate in terms of power requirements, but they still don't have a compatible plug.
- The supplier I eventually found - Power Adapters UK (they do "exactly what it says on the tin") - carry a large range of power supplies and adapters, with images and dimensions of each item. They probably won't recommend an adapter for a specific device, so knowing the correct dimensions is important. They told me they only had a limited stock of the 5.5 x 2.1mm pin to 5.5mm o/d x 3mm pin adapter - but I only wanted 3 and they consider 100 limited stock, so no problem there 🙂
