I got 2 usb chargers from Amazon with multiple ports & does work on the Nook HD+ for me.
1) iXCC ® Dual USB 4.2 Amp (20 Watt) SMART High Capacity [High Power] AC Travel Wall Charger - ChargeWise (tm) Technology [High Speed] FAST Charging for Apple iPhone 5s 5c 5; ipad air; iPad Air mini (Retina Display); iPad 4; ipad2; Samsung Galaxy S5 S4 S3; Note 2 and Note 3; the new HTC One (M8); Google Nexus and More [Black]. I got the Blue model.
2) Anker® 40W 5-Port Family-Sized Desktop USB Charger with PowerIQ™ Technology for iPhone 5s 5c 5; iPad Air mini; Galaxy S5 S4; Note 3 2; the new HTC One (M8); Nexus and More (White) May be overkill for some.
Found that the SIIg usb 2 amp charger won't work or get recognized by the Nook HD+; it's marketed as for the crapple's ipod/ipad. A signal of incompatibility is if it says for Apple products.
