What we liked
- + USB power means you can charge from a power bank or laptop
- + XH-3P balance plug matches common 2S pack balance leads
- + Simple plug-in charging with no charger settings to learn
Trade-offs
- - USB charging is slow compared with a proper balance charger
- - Limited to 7.4V packs, so larger batteries need a real charger
