CyberPower battery back-up
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought to replace a 6 year old one of the same brand that stopped working. Order process was simple and device arrived when expected. The outlet orientation was rotated 90 degrees from prior the prior unit and it made 'plugging in' a bit of a jigsaw puzzle. Orientation makes sense if just a plug but 4 of my 7 devices had mini-transformers (bulkly) instead of a pure plug.

Best Battery Backup
