- Reviewed in the United Kingdom on 26 October 2017Size Name: 6.6 ft/2 mStyle Name: Type MVerified PurchaseWorking well so far, using to power an M8S Mini android box direct from the TV, always find that Android boxes come with a tiny wire that are never long enough, this solves that problem.
- Reviewed in the United Kingdom on 30 July 2024Size Name: 3ft/1mStyle Name: Type HVerified PurchaseI lost the charger to this product only a couple of months after buying it. I wrote to the manufacturer and they kindly told me where I can buy a new one. Great service great value for money.
- Reviewed in the United Kingdom on 8 August 2024Size Name: 3 ft/90 cmStyle Name: Type MVerified PurchaseBought this as a replacement MiniRig charger, it does work but sometimes the cable must be held in a certain position. Not the best quality, not the worst.
- Reviewed in the United Kingdom on 29 March 2013Size Name: 3ft/1mStyle Name: Type HVerified PurchaseI have an Archos G9 10.1 inch 250Gb Tablet which has a dedicated power supply. I wanted a single USB charge I could use for all devices, so I needed a separate USB powers supply lead. Unfortunately Archos don’t seem to publish the specifications for the plug on the power lead. I bought 2 different leads to see if they would fit, then measured all the plugs (including the Archos supplied power supply) using a set of callipers at 3.4mm to 3.5mm in diameter. They both work fine and are capable of charging the table.
If you are interested the other lead can be found at this link:-
http://www.amazon.co.uk/gp/product/B007TLQF0W/ref=oh_details_o06_s00_i00?ie=UTF8&psc=1
Note the Archos power supply is capable of supplying 2A. Both these leads were capable of supplying this. However if you are buying a power supply for a high power tablet or phone, you must ensure both the power supply and lead are capable of supplying the necessary power. I have a number of old USB power supplies and they are not capable of charging the tablet even though the lead is.
