We compared two universal travel plug adapters: the AUNNO Universal Travel Adapter and the TESSAN Universal Travel Adapter Worldwide.
What we looked at
Rated power, USB port count, and price.

If you want the lower price on a compact all-in-one adapter rated up to 2400W with an intelligent IC chip, the AUNNO is the value pick, at £14.43. If you would rather pay £5.56 more for a design covering over 224 countries with double fuse protection, the TESSAN is the alternative, at £19.99 — both offer 2 USB-C and 2 USB-A ports.
