The UniQue generic replacement Acer laptop charger is a 45W adapter for Acer notebooks that run on 19V and use the small 3.0 x 1.1mm DC connector. This size of tip is common on thinner Acer Aspire, Swift, Switch and Chromebook models. It outputs 19V at 2.37A and accepts a 100-240V, 50/60Hz input, so it runs from South African mains and overseas supplies alike, and it comes with a clover (figure-8) mains cable. Esquire lists compatibility with models including the Aspire R5-471T/R5-571T, R7-371T/R7-372T, S5-371, S7-392, V3-331/V3-371/V3-372, the Aspire One Cloudbook 1-131/1-431 and Aspire Switch SW5-171/SW5-173/SW7-271, but always confirm against your original charger: 19V output, 3.0 x 1.1mm tip and 45W (2.37A) or less. Good as a spare to keep at work or as a replacement for a lost or faulty adapter. Retail box, 6-month warranty.
